A smart second skin gets all the power it needs from sweat

The big idea Skin is the largest organ of the human body. It conveys a lot of information, including temperature, pressure, pleasure and pain. Electronic skin (e-skin) mimics the properties of biological skin. Recently developed e-skins are capable of wirelessly monitoring physiological signals. They could play a crucial role in the next generation of robotics and medical devices. My lab at Caltech is interested in studying human biology and monitoring human health by using advanced bioelectronic devices. The e-skin we have developed not only analyzes the chemical and molecular composition of human sweat, it’s fully powered by chemicals in sweat. Why it matters Existing e-skins and wearable devices primarily focus on monitoring physiological parameters like heart rate and can’t assess hea...
