A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it. What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still -- no exercise required!
