Wearable air conditioning without needing electricity

Nanowerk  January 6, 2019 By using multiscale porous Styrene-ethylene-butylene-styrene (SEBS) as supporting substrates a team of researchers in the US (University of Missouri, Argonne National Laboratory) has developed multifunctional on-skin electronics with outstanding passive-cooling capabilities, delivering around 6 °C cooling effects under a solar intensity of 840 W⋅m−2. Other desired properties, rooted in porous SEBS substrates, include high breathability and outstanding waterproofing. In addition, a variety of bioelectronic devices are made on porous SEBS substrates via spray printing of silver nanowires. The enabled devices demonstrate high performance and are recyclable. Currently, the device is a small wired patch, and researchers […]

Self-powered wearable tech

Science Daily  May 2, 2019 An international team of researchers (USA – State University of Michigan, Duke University, Naval Research Laboratory, MIT, China) has created highly stretchable supercapacitors which has demonstrated solid performance and stability, even when it is stretched to 800% of its original size for thousands of stretching/relaxing cycles. Instead of having a flat thin film strictly constrained during fabrication, their design enables the three-dimensionally interconnected CNT forest to maintain good electrical conductivity, making it much more efficient, reliable and robust. The research may spur the development of new stretchable energy electronic systems, implantable biomedical devices, as well […]
