Researchers develop rGO-enhanced structural supercapacitor
We’re seeing real progress in our vision to infuse
circuits into conductive fibers.
(ed.)
Researchers from the University of
California San Diego and the University of Southern Mississippi recently
designed a graphene-enhanced structural supercapacitor. Structural
supercapacitors hold promise to expand the energy capacity of a system by
integrating load-bearing and energy-storage
functions in a multifunctional structure, resulting in weight savings and
safety improvements. As a proof of concept, the researchers used their structural
supercapacitor to build a miniature solar-powered boat. The supercapacitor
was molded to form the boat’s hull and then fitted with a small motor
and circuit. The circuit was connected to a solar cell. When exposed to
sunlight, the solar cell charges the supercapacitor, which in turn powers the
boat’s motor. In tests, the boat was able to cruise across the water,
demonstrating the efficacy of this innovative energy storage solution. more Also related article

What if a car frame,
boat hull, or phone case could store energy Using a clever combination of materials and
design, engineers have made a battery-like device that is strong enough to
provide mechanical support. A new
battery-like energy-storing device is also tough enough to provide protection
and mechanical support. The device could lead to extra power stored in
structures such as phone cases, electric vehicle frames and ship hulls. That would
mean EVs that drive longer between charges, powered partly
by the material they are built from. “This can extend the operational
time of electronic systems, like in submersibles for ocean explorations or in
consumer electronics—imagine longer operating time for airpods,” says Tina Ng, a materials science and
engineering professor at the University of California San Diego. The device
that Ng and her colleagues reported in the journal Science Advances is a
supercapacitor. Much like batteries, supercapacitors are energy-storing
devices with two electrodes and an electrolyte. The two devices complement
each other, because batteries can deliver energy for a long time, while
supercapacitors provide quick bursts of power for things like acceleration. Both types of
devices hold a limited amount of charge, though. So researchers have been
trying to find ways to integrate batteries and supercapacitors into building materials for low-cost technologies to store energy. Carbon fibers
are a promising material for this because they are strong and durable, and
they can also conduct electricity. Carbon fiber laminates are
commonly used to make boat hulls already, so adding energy storage
capacity to them was a logical step, Ng says. more |

Bioengineers Develop Spider Web-Inspired
Method to Fabricate Conductive Fibers Advance could lead to
energy-efficient, low-cost smart textiles Using
a new process that mimics how spiders spin silk, a UCLA-led team of
multi-institutional bioengineers has developed a simple process to make soft,
electrically conductive fibers at room temperature and atmospheric pressure. In a study published as a cover story in Nature Electronics, the
researchers demonstrated their technique with a sensing glove and a smart
face mask made with the stretchable and durable fabrics. The glove can sense
temperatures and hand motions for the user to play a
“rock-paper-scissors” computer game, while the mask is able to
monitor the individual’s breathing patterns. more |

Interfacial Capillary Spooling of
Conductive Polyurethane–Silver Core–Sheath (PU@Ag)
Microfibers for Highly Stretchable Interconnects
Conductive fibers are
core materials in textile electronics for the sustainable operation of
devices under mechanical stimuli. Conventional polymer–metal
core–sheath fibers were employed as stretchable electrical
interconnects. However, their electrical conductivity is severely degraded by
the rupture of metal sheaths at low strains. Because the core–sheath
fibers are not intrinsically stretchable, designing a stretchable
architecture of interconnects based on the fibers is essential. Herein, we
introduce nonvolatile droplet–conductive microfiber arrays as
stretchable interconnects by employing interfacial capillary spooling,
motivated by the reversible spooling of capture threads in a spider web. (more) |

Simulation of electrical conductivity for
polymer silver nanowires systems A simple model is developed for the
conductivity of polymeric systems including silver nanowires (AgNWs). This model reveals the effects of interphase
thickness, tunneling distance, waviness and aspect
ratio of nanowires, as well as effective filler volume fraction on the
percolation and electrical conductivity of AgNW-reinforced
samples. The validity of this model is tested by using the measured data from
several samples. Based on this model, the conductivity calculations are in
proper accordance with the measured values. A large network and a low
percolation onset are produced by nanowires with a high aspect ratio
developing the nanocomposite conductivity. The results also show that a
thicker interphase expands the network, thereby increasing the electrical
conductivity. Furthermore, non-waved AgNWs exhibit
more conductivity compared to wavy nanowires. It is concluded that the
surface energies of polymer medium and nanowires have no effect on the
conductivity of samples. On the other hand, the volume fraction and aspect
ratio of nanowires, in addition to the interphase thickness and tunneling
distance have the greatest influences on the conductivity of
nanocomposites. (more) |

Preparation of Palladium/Silver-Coated Polyimide Nanotubes: Flexible,
Electrically Conductive Fibers A simple and practical method for coating
palladium/silver nanoparticles on polyimide (PI) nanotubes is developed. The
key steps involved in the process are silver ion exchange/reduction and
displacement reactions between silver and palladium ions. With the addition
of silver, the conductivity of the PI nanotubes is greatly enhanced. Further,
the polyimide nanotubes with a dense, homogeneous coating of palladium
nanoparticles remain flexible after heat treatment and show the possibility
for use as highly efficient catalysts. The approach developed here is
applicable for coating various noble metals on a wide range of polymer matrices, and can be used for obtaining polyimide
nanotubes with metal loaded on both the inner and outer surface. (source) |

Could Wood Replace Our Need for Wires? Amazing idea--ed. Functionalization—the scientific term for the addition of new functions to an existing material—is a common technique in materials science, chemistry, and nanotechnology. In architecture, function is often considered at an assembly, system, or spatial level. Although functionalization research commonly involves polymers, glass, and metal oxides, some researchers and designers are adding new functions to wood. In this case, function is added to the wood itself by surface manipulations. The approach is used to modify characteristics like color, hydrophobicity, magnetism, and antimicrobial properties, often transforming the material. more |

Stronger than spider silk: Bagworm silk enables strong conducting fibers Think spider silk is strong? Recent work has shown that bagworm silk is superior to spider silk in both strength and flexibility. Building on these findings, a research team at the University of Tsukuba, led by Professor Hiromasa Goto, has harnessed the strength of bagworm silk to produce a strong, flexible, conductive fiber. This research may lead to new flexible electronic devices, such as wearable electronic materials. Owing to its high flexibility and strength, spider silk has received much attention for uses ranging from medicine to aerospace applications. By combining natural silk, such as spider silk, with synthetic conductive polymers, researchers can produce textiles with conduction, light emission, and photovoltaic functions. It is also possible to create biocompatible materials that can be used in regenerative medicine and biomedical materials. "We've taken the next step from previous research efforts by utilizing the strongest known natural fiber—bagworm silk," explains Professor Goto. more |

Counterfeiting: A Global Fake Out RESEARCH TRIANGLE PARK, N.C., USA, July 20, 2021-Counterfeiting and piracy are global issues. The United States, France, Switzerland, and Germany were most affected by counterfeiting activity in a 2016 study; however, increases were noted in Singapore, Hong Kong, Brazil, China, and other emerging markets. (OECD, 2019) Countries worldwide are impacted by product fakes in the marketplace. Counterfeit comes with high economic and monetary losses. It is estimated that counterfeit goods in the US alone cost the economy US$600 Billion per year, which is roughly 3% of Gross Domestic Product. (Schlesinger, 2019) According to the Trends in Trade in Counterfeit and Pirated Goods report issued by OECD.org, in the European Union alone, counterfeit trade represented 6.8% of imports from non-EU countries. These figures do not include domestically produced counterfeit goods or pirated products distributed over the Internet. (OECD, 2019) |

Washability of E-Textiles: Failure Modes and Influences on Washing Reliability Abstract E-textiles, hybrid products that incorporate electronic functionality into textiles, often need to withstand washing procedures to ensure textile typical usability. Yet, the washability—which is essential for many e-textile applications like medical or sports due to hygiene requirements—is often still insufficient. The influence factors for washing damage in textile integrated electronics as well as common weak points are not extensively researched, which makes a targeted approach to improve washability in e-textiles difficult. As a step towards reliably washable e-textiles, this review bundles existing information and findings on the topic: a summary of common failure modes in e-textiles brought about by washing as well as influencing parameters that affect the washability of e-textiles. The findings of this paper can be utilized in the development of e-textile systems with an improved washability. View Full-Text |

Effects of surface condition of conductive electrospun nanofiber mats on cell behavior for nerve tissue engineering Abstract. Electrospun nanofibrous scaffold is a promising implant for peripheral nerve regeneration. Herein, to investigate the effect of surface morphological features and electrical properties of scaffolds on nerve cell behavior, we modified electrospun cellulose (EC) fibrous mats with four kind of soluble conductive polymers derivates (poly (N-(methacryl ethyl) pyrrole) (PMAEPy), poly (N-(2-hydroxyethyl) pyrrole) (PHEPy), poly (3-(Ethoxycarbonyl) thiophene) (P3ECT) and poly (3-thiophenethanol) (P3TE)) by an in-situ polymerization method. The morphological characterization showed that conductive polymers formed aggregated nanoparticles and coatings on the EC nanofibers with the increased fiber diameter further affected the surface properties. Compared with pure EC scaffold, more PC12 cells were adhered and grown on modified mats, with more integral and clearer cell morphology. The results of protein adsorption study indicated that modified EC mats could provide more protein adsorption site due to their characteristic surface morphology, which is beneficial to cell adhesion and growth.

Perfect for Earth Day, 2020 Flexible electronics made with wood-based nanotechnology Nanowerk Spotlight) Wood has been traditionally used as lumber or has been deconstructed into elemental fibrils before being reconstructed into various material such as paper, cardboard and artificial wood-based products. More recently, nanocellulose from wood – a nanomaterial derived from breaking wood fibers down to the nanoscale – has found additional applications such as strength enhancers in paper and biocomposites, barriers for packaging, emulsifiers, in oil separation, substrates for printing electronics, filtration, and biomedicine. "Wood nanotechnologies are not only associated with extraction and use of nanocellulose or lignin but also with tailoring and functionalizing the hierarchical nanostructure of bulk wood for functional materials," Qiliang Fu, a Wood and Fiber Scientist at Scion, a New Zealand government research institute, tells Nanowerk. "In our latest research we use a top-down approach with a mild chemical treatment that allows the preservation of the complex structure and the original orientation of the cellulose fibres. By conserving the wood structures, a highly aligned cellulosic material with excellent strength is achieved." more |

Assembly of graphene oxide on cotton fiber through dyeing and their properties Materials with electrical conductivity are preferred for electronics, medical, space and other applications. Flexible, stretchable and washable conductive fabrics have been preferred over metallic materials. However, the currently available conductive fabrics are mainly made using a dip-drying process which makes it difficult to obtain a regular assembly structure of graphene sheets on the fibers. In this research, we report the development of conductive cotton fabrics through simple dyeing, graphene oxide (GO) with two distinct sizes was used to dye the fabrics which were later reduced using hydrazine hydrate. The regularity of graphene sheets on the surface of the cotton fiber can be improved by level assembly, it is beneficial to the conductive stability of the later drawing, bending and friction process. The results show that, the fabrics coated with graphene had excellent fastness to washing, friction and bending. After 20 washings and exposure to 2000 rubbing and 1000 bending cycles, the fabrics had excellent conductivity retention of 86%, 55% and 99%, respectively. In addition, the introduction of graphene causes the dyed fabric to have good infrared absorption and excellent UV resistance. Using cotton fabrics and GO to impart conductivity and UV resistance would be an affordable, sustainable and novel approach to develop functionalized materials for various applications. more/citation |

Electrical conductivity of anisotropic PMMA composite filaments with aligned carbon fibers – predicting the influence of measurement direction In order to study the electrical conductivity of anisotropic PMMA/carbon fiber (CF) composites, cylindrical PMMA/CF filaments were extruded through a capillary rheometer, resulting in an induced CF orientation along the extrusion direction. The aspect ratios of the CFs in the filaments were accurately regulated using a two-step melt mixing process. By measuring the vertical and horizontal resistances of filaments where the outermost layer was successively peeled off, the anisotropic conductivities could be calculated. This was done using a novel analytical model where each cylindrical composite filament was defined as a structure consisting of three concentric cylinders with potentially different conductivities and CF orientations. The electrical conductivity increased with the degree of fiber orientation along the voltage direction and the effects of anisotropy and measurement direction were incorporated into the (isotropic) McLachlan equation. The required distance for electrical contact between the CFs was calculated to be 16 nm. Finite element (FEM) simulations were successfully utilized to confirm the data. Citation&MORE |

Causes Of Electrostatic Phenomena In Textiles And Antistatic Methods In the textile production process, static electricity will affect the quality of spinning and weaving products, and even affect the dyeing and finishing process. For example, after drying, the moisture content of fabric decreases, and it is not easy to generate static electricity. It is often adsorbed on metal parts, and there is a disorder winding phenomenon. Because the same fabric has the same charge and mutual exclusion, the falling cloth is not easy to fold and neatly, which affects the processing of the lower track. The operator's hand and the contact with the charged dry cloth are often subjected to electric shocks. The clothing with static electricity is easy to absorb dust and pollute. After taking the clothes with static electricity, they will be entangled with each other, and the phenomenon of "skirt embracing legs" will cause mutual discomfort. Citation&More |

Axial alignment of carbon nanotubes on fibers to enable highly conductive fabrics for electromagnetic interference shielding Conductive coatings show great promise for next-generation electromagnetic interference (EMI) shielding challenges on textile; however, their stringent requirements for electrical conductivity are difficult to meet by conventional approaches of increasing the loading and homogeneity of conductive nanofillers. Here, the axial alignment of carbon nanotubes (CNTs) on fibers that obtained by spontaneous capillary-driven self-assembly is shown on commercial cotton fabrics and its great potential for EMI shielding is demonstrated. The aligned CNTs optimize structurally the conductive network on fabrics and yield an 81-fold increase in electrical conductivity per unit CNT, compared with the disordered CNT microstructure. The high-efficiency electrical conductivity allows a several-micron-thick coating on insulating fabrics to endow an EMI shielding effectiveness of 21.5 dB in the X band and 20.8 dB in the Ku band, respectively, which meets the standard shielding requirement in commercial applications. It is among the minimum reported thicknesses for conductive nanocomposite coatings to date. Moreover, the coated fabrics with aligned CNTs possess a desirable stability upon bending, scratching, stripping and even washing, which is attributed to the dense CNT packing in the aligned microarchitecture. This work presents the anisotropic structure on large areas by self-assembly, offering new opportunities for next-generation portable and wearable electronic devices. Citation&More |

Statex and V Technical Textiles Announce the Availability of a New Textile-Based Circuitry Technique V Technical Textiles, Inc. and our European Partner, Statex Produktions-und Vertriebs GmbH, and have announced the availability of a Selective Plating Technique, a joint technology developed by our European Partner Statex and Laird Performance Materials. This technology will not only create the ability to selectively silver plate an electrically conductive pattern or circuit on to both sides of a flexible fabric substrate but literally through all three dimensions of the fabric, including top and bottom sides and the fabric in between the sides. This has helped in the durability of the plating when subjected to multiple stretch and wash processes, which has always been a difficulty with the traditional screen printed conductive ink processes. The new technology has passed rigorous testing involving stretching and washing cycles with no noticeable negative effects in electrical performance. This improved technique could well be used
in situations requiring low amperage flexible circuits that are particularly
useful in the medical field when sensors are attached to a flexible human
substrate, the skin. These circuits will also be useful in
touch-activated switches, and patch antennas in the automotive, aerospace,
military, telecommunications, and smart textiles industries and in
combination with other electronic devices. Combined with “silverized yarn wires” covered with Thermoplastic PolyUrethane (TPU) to provide durable, flexible
connections for these circuits, the potential uses for this new technology
are almost endless. Please contact us with your ideas for this new
technology and we’ll be happy to help you design and develop your
product from conception to prototype and through to production!

Boosting wearable signals Researchers at the National University of Singapore and University of Waterloo developed a conductive textile that can be used in clothing to boost the communications power of wearable devices and sensors. The team says such a ‘wireless body sensor network’ allows devices to transmit data with 1,000 times stronger signal, improving device battery life. Typically, wearable devices use Bluetooth or Wi-Fi to report back to the user’s smartphone. As they broadcast several meters in all directions, energy is lost to the surrounding environment. Instead, when woven into clothing, the team’s metamaterial textile is able to create ‘surface waves’ which can glide wirelessly around the body such that the energy of the signal between devices is held within 10 centimeters of the body rather than spread in all directions. more |

Electrically Conductive Coatings for Fiber-Based E-Textiles Kony Chatterjee, Jordan Tabor and Tushar K. Ghosh * Department of Textile Engineering, Chemistry and Science, Wilson College of Textiles, North Carolina State University, Raleigh, NC 27606, USA; kchatte@ncsu.edu (K.C.); jatabor@ncsu.edu (J.T.)* Correspondence: tghosh@ncsu.edu; Tel.: +1-919-515-6568 Abstract: With the advent of wearable electronic devices in our daily lives, there is a need for soft, flexible, and conformable devices that can provide electronic capabilities without sacrificing comfort. Electronic textiles (e-textiles) combine electronic capabilities of devices such as sensors, actuators, energy harvesting and storage devices, and communication devices with the comfort and conformability of conventional textiles. An important method to fabricate such devices is by coating conventionally used fibers and yarns with electrically conductive materials to create flexible capacitors, resistors, transistors, batteries, and circuits. Textiles constitute an obvious choice for deployment of such flexible electronic components due to their inherent conformability, strength, and stability. Coating a layer of electrically conducting material onto the textile can impart electronic capabilities to the base material in a facile manner. Such a coating can be done at any of the hierarchical levels of the textile structure, i.e., at the fiber, yarn, or fabric level. This review focuses on various electrically conducting materials and methods used for coating e-textile devices, as well as the different configurations that can be obtained from such coatings, creating a smart textile-based system. |

Next-generation composites may monitor their own structural health (ed: wonder if we can translate this to fibers also?) Carbon fiber composites—lightweight and strong—are great structural materials for automobiles, aircraft and other transportation vehicles. They consist of a polymer matrix, such as epoxy, into which reinforcing carbon fibers have been embedded. Because of differences in the mechanical properties of these two materials, the fibers can detach from the matrix under excessive stresses or fatigue. That means damage in carbon fiber composite structures can remain hidden below the surface, undetectable by visual inspection, potentially leading to catastrophic failure. more also here |

Its high conductance and high electron mobilities have tantalized engineers with the possibilities of future electronics applications. CNT’s physical strength has led to predictions of new materials, particularly super strong threads, yarns and cables. Although progress has been made in the laboratory, industrialized production of CNTs has been elusive. more |

New conductive coating may unlock biometric and wearable technology of the future A team of researchers from the College of Engineering at Texas A&M University have developed a mechanically robust conductive coating that can maintain performance under heavy stretching and bending. Stretchable, bendable and foldable electronics are crucial for the development of emerging technologies like adaptive displays, artificial skin, and biometric and wearable devices. This presents a unique challenge of balancing electronic performance and mechanical flexibility. The difficulty lies in finding a material that can withstand a wide array of deformations, like stretching, bending and twisting, all while maintaining electrical conductivity. Adding to the challenge is the need for this conductivity to be engineered into a variety of different surfaces, such as cloth, fiber, glass or plastic. more |

Flexible, sensor-packed e-skin can be healed when damaged and recycled when no longer needed The next generation of fitness trackers and health monitors may not be little boxes we wear around our necks or on our wrists, they could be flexible wearables or temporary tattoos. But when such devices get damaged, they'll need to be replaced. And when they're no longer needed, they'll end up on the growing mountain of e-waste. Researchers from the University of Colorado Boulder have developed an electronic skin embedded with a host of sensors that can be bent and twisted to custom fit its owner. And if it gets damaged, the e-skin can be healed, and it can be completely recycled at the end of its useful life. link |

Reconstituted silk can be several times stronger than the natural fiber and made in different forms When it comes to concocting the complex mix of molecules that makes up fibers of natural silk, nature beats human engineering hands down. Despite efforts to synthesize the material, artificial varieties still cannot match the natural fiber's strength. But by starting with silk produced by silkworms, breaking it down chemically, and then reassembling it, engineers have found they can make a material that is more than twice as stiff as its natural counterpart and can be shaped into complex structures such as meshes and lattices. more |

Tods Aerospace finalist for materials innovation award UK-based Tods Aerospace has collaborated with Technical Fibre Products (TFP) to develop a nonwoven veil for static dissipation applications. The innovation was developed to overcome the limitations of current state-of-the-art products available in the market and is tailored for composite applications in commercial and military aircraft fuel systems. The resulting technology, a nonwoven veil material, comes from an industry collaboration between Tods Aerospace and Technical Fibre Products (TFP, Kendal, Cumbria, UK). “Electrostatic dissipation is a requirement for nearly all glass-based composite materials used in fuel systems for modern composite-wing aircraft,” says Sean Cooper, materials and manufacturing development manager for Tods Aerospace. “Low-level electrical conductivities are required to prevent a buildup of static charge in the structure and prevent the propagation of electrical effects through the fuel system during an external lightning strike. This process of electrostatic management is an absolute necessity to ensure the safe operation of the aircraft.” more |

Wearable sensors reach their first billion-dollar year, with growth coming in three waves By Mr James Hayward, Senior Technology Analyst, IDTechEx www.IDTechEx.com IDTechEx predict that 2017 will be the first billion dollar year for wearable sensors. These critical components are central to the core value proposition in many wearable devices. The "Wearable Sensors 2018-2028: Technologies, Markets & Players" report includes IDTechEx's latest research and forecasts on this topic, collating over 3 years of work to provide a thorough characterisation and outlook for each type of sensor used in wearable products today. Despite sales volumes from wearable products continuing to grow, creeping commoditisation squeezes margins, with hardware sales being particularly vulnerable. This has led to some consolidation in the industry, with several prominent failures and exits, and challenging time even amongst market leaders in each sector. As hardware margins are squeezed, business models are changing to increasingly focus on the valuable data generated once a device is worn. Sensors are responsible for the collection and quality of that data, so understanding the capabilities and limitations of different sensor platforms is critical to understanding the progress of the industry as a whole. In the report, IDTechEx address 21 different types of wearable sensor across 9 different categories as follows: Inertial Measurement Units (IMUs), optical sensors, electrodes, force/pressure/stretch sensors, temperature sensors, microphones, GPS, chemical & gas sensors & others. Hundreds of examples from throughout the report cover a breadth of technology readiness, ranging from long-established industries to early proof-of-concepts. The report contains information about the activities of over 115 different companies, with primary content (including interviews, exhibition or site visits by the authors) to more than 80 different companies, large and small. IDTechEx describe wearable sensors in three waves. The first wave includes sensors that have been incorporated in wearable for many years, often being originally developed for wearable products decades ago, and existing as mature industries today. A second wave of wearable sensors came following huge technology investment in smartphones. Many of the sensors from smartphones could be easily adapted for use in wearable products; they could be made-wearable. Finally, as wearable technology hype and investment peaked, many organisations identified many sensor types that could be developed specifically with wearable products in mind. These made-for-wearable sensors often remain in the commercial evaluation or relatively early commercial sales today, but some examples are already becoming significant success stories. Billions of wearable electronic products are already sold each year today. Many have already experienced significant hardware commoditisation, with tough competition driving prices down. Even as wearable devices become more advanced, introducing more sensors and better components to enhance value propositions, lessons of history tell us that hardware will always be prone to commoditisation. As this happens the role of sensors only becomes more important; with hardware prices being constantly squeezed, increasing proportions of the value that companies can capture from products will be from the data that the products can generate. The key hardware component for capturing this data is the sensors, so understanding the development and prospects of sensors today is critical to predicting the potential for this entire industry in the future. "Wearable Sensors 2018-2028: Technologies, Markets & Players" is written to address the needs of any company or individual looking to gain a clearer, independent perspective on the outlook for various types of wearable sensor. The report answers detailed questions about technology, markets and industry trends, and supported by years of primary research investment collated and distilled within. |

Three-Dimensional Highly Stretchable Conductors from Elastic Fiber Mat with Conductive Polymer Coating The manufacture of stretchable conductors with well-reserved electrical performance under large-degree deformations via scalable processes remains of great importance. In this work, a highly stretchable 3D conductive framework consisted of polyurethane fiber mat (PUF) and poly(3,4-ethylenedioxythiophene) (PEDOT) is reported through facile approaches, electrospinning and in situ interfacial polymerization, which was then backfilled with poly(dimethylsiloxane) to obtain 3D conductors. The excellent stretchability of the 3D conductive network imparted the as-prepared electrode superior mechanical durability. What’s more, the applied strains can be effectively accommodated by the arrangement and orientation of the fibers resulting in relatively stable electrical performance with only 20% increased resistance at 100% stretching. Meanwhile, the resistance of the conductor could keep constant during 2000 times of bending and showed slightly increase during 100 times of 50% stretching. The potential in the applications of large-area stretchable electrodes were demonstrated by the construction of LED arrays with the PUF based conductors as electrical connections. link |

The proposed invention relates to a conductive fiber material that has been obtained starting from a textile fiber, that can be natural or artificial. Such fiber can be modified by functionalization with metal nanoparticles and by treatment with a conductive polymer. Both these treatments contribute to make this fiber conductive at the level of a metal wire, thus enabling the use of these fibers for making electrical connections in textile forms. In addition, starting from this fiber, also the concept of textile transistor has been
developed, thus providing the basic block of any complex electronic
