Electricity, eel-style: Soft power cells could run tomorrow's implantables http://www.ns.umich.edu/new/multimedi... “Inspired by the electric eel, a flexible, transparent electrical device could lead to body-friendly power sources for implanted health monitors and medication dispensers, augmented-reality contact lenses and countless other applications. The soft cells are made of hydrogel and salt, and they form the first potentially biocompatible artificial electric organ that generates more than 100 volts.”
Stretchable Solar Batteries May Power the Next Generation of Wearable Devices https://www.seeker.com/tech/stretchab... “In recent years, electronic devices have migrated into all sorts of strange areas — smart underwear, for instance, that can measure your heart rate, calorie consumption, and posture. As such, batteries are changing too. Researchers at the University of California, Berkeley have developed a new kind of stretchy battery specifically designed for wearable devices and clothing that require more flexibility than old-school electronics.”
Chasing the ‘Holey’ Grail of Batteries https://www.seeker.com/tech/materials... “This week, a team of researchers from the United States, China, and Saudi Arabia unveiled a new type of battery electrode made with “holey” graphene. In a paper published in Science, the researchers describe a porous form of graphene — the world’s thinnest and lightest nanomaterial — that overcomes some key challenges in creating next-generation batteries.”
