Skin-based biofuel cell developed for scavenging energy from human sweat

(Tech Xplore)—A team of researchers at the University of California has developed a skin patch that uses human sweat as a fuel source to power an external device. In their paper published in the journal Energy & Environmental Science, the team describes how they built their patch and how well it works.
Scientists and engineers are convinced that consumers want easy-to-wear consumer products—health monitors that are built into clothes, for example, or that adhere to the skin. To that end, teams around the world have been developing bendable products with associated batteries, or better still, devices that do not need batteries because they get a constant stream of power from the person wearing them. In this new effort, the researchers have found a way to harness human sweat as an energy source and report that the device they built was able to power a Bluetooth transmitter.
