Soft, stretchable, high power density electronic skin-based biofuel cells for scavenging energy from human sweat that can power BLE radio, LEDs etc

A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10X more power per surface area than any existing wearable biofuel cells. The epidermal biofuel cells are a major breakthrough in the field, which has been struggling with making the devices that are stretchable enough and powerful enough. UCSD engineers used a combination of clever chemistry, advanced materials and electronic interfaces...
