Amay J. Bandodkar et al. Soft, stretchable, high power density electronic skin-based biofuel cells for scavenging energy from human sweat, Energy Environ. Sci. (2017). DOI: 10.1039/C7EE00865A
A team at the University of California has developed a skin patch that uses human sweat as a fuel source to power an external device. 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. In this new effort, they 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.
Sweat can be used as an energy source because it contains lactate, which produces energy when it oxidizes with lactate oxidase...
