Solar supercapacitor could power wearable sensors

According to researchers from the University of Glasgow’s Bendable Electronics and Sensing Technologies group, a new form of solar-powered supercapacitor could help make future wearable technologies lighter and more energy-efficient. Currently, wearable systems generally rely on relatively heavy, inflexible batteries that can be uncomfortable for long-term users. The supercapacitor uses layers of flexible, three-dimensional porous foam formed from graphene and silver to produce a device capable of storing and releasing around three times more power than any similar flexible supercapacitor. The team demonstrated the durability of the supercapacitor, showing that it provided power consistently across 25,000 charging and discharging cycles.
