Laser-induced graphene composites are eminently wearable

flexible-electronicsTo realize the commercial potential of graphene, for instance for wearable electronics, it is necessary to develop reliable, cost-effective and facile processes for the industry-scale fabrication of graphene-based devices. A novel solution involves the synthesis of high-performance stretchable graphene ink using a facile, scalable, and low-cost laser induction method for the synthesis of the graphene component. This also is the first example of using laser-induced graphene in the form for a powder preparation of graphene-based inks and subsequently for use in screen-printing of stretchable micro-supercapacitors.

Weaving carbon nanotube wires into high-performance, wearable supercapacitors

textile-batteryResearchers have developed a comprehensive approach involving simple and facile steps to fabricate a wearable energy storage device based on carbon nanotube coated cotton yarn. All device components are flexible. According to the team, this is the first device that has been proven to be stable under rigorous washing conditions in the presence of hot water, detergents and high torque (spinning action of washing machine). This provides the device with comprehensive mechanical stability.

Graphene and silk combine to make self-healable, multifunctional electronic tattoos

e-tattooElectronic tattoos (e-tattoos) are an extremely thin form of wearable electronics. They are lightweight and soft, which allows them to be intimately mounted on human skin for noninvasive, high-fidelity sensing. During the operation of e-tattoos, they are constantly exposed to external mechanical inputs such as bending, twisting, pressing, and cutting, which may cause mechanical damage and lead to malfunction. Now, researchers have demonstrated a self-healing silk e-tattoo that shows high sensitivity to multiple stimuli, including strain, humidity, and temperature based on a unique graphene, silk fibroin, Ca2+ combination.

Green and flexible protein-based electronics

e-gloveIonic conductors are a class of materials with key roles in energy storage, solar energy conversion, sensors, and electronic devices. In their quest towards eco-friendly alternatives for the current type of ionic conductors, researchers have developed an alternative green option based on organic silk and inorganic green laponite for the display and wearables industry via flexible and eco-friendly ionics. This could ultimately enable a wide range of applications within the field of flexible and wearable electronics.

Power up your T-shirt with print designs

electronic_t-shirtInspired by the designs printed on T-shirts, researchers recently reported a new class of wearable power sources. To explore the feasibility of power sources directly printed on cotton T-shirts, which look like letters or symbols, they chose electric double layer supercapacitors based on activated carbon materials as a model electrochemical system. These T-shirts look and behave like a normal T-shirt but feature printed supercapacitors in the shape of letters and symbols.

Revolutionizing smart textile nanofinishing in a green fashion

smart_textileA major challenge in nanotechnology is that of determining how to introduce green and sustainable principles when assembling individual nanoscale elements to create working devices. For instance, textile nanofinishing is restricted by the many constraints of traditional pad-dry-cure processes, such as use of costly chemical precursors to produce nanoparticles, high liquid and energy consumption, production of harmful liquid wastes, and multistep batch operations. By integrating low-cost, scalable, and environmentally benign aerosol processes, these constraints can be circumvented while leading to a new class of multifunctional fabrics.

Nanotechnology in textiles - the new black

shirtNanoengineered functional textiles are going to revolutionize the clothing that you'll wear. The potential of nanotechnology in the development of new materials in the textile industry is considerable. This review discusses electronic and photonic nanotechnologies that are integrated with textiles and shows their applications in displays, sensing, and drug release within the context of performance, durability, and connectivity. On the one hand, existing functionality can be improved using nanotechnology and on the other, it could make possible the manufacture of textiles with entirely new properties or the combination of different functions in one textile material.
