One of the ways we experience the world around us is through our skin. From sensing temperature and pressure to pleasure or pain, the many nerve endings in our skin tell us a great deal. Our skin can also tell the outside world a great deal about us as well. Wei Gao, Assistant Professor of Medical Engineering has developed an electronic skin, or e-skin, that is applied directly on top of your real skin. "We want this system to be a platform," he says. "In addition to being a wearable biosensor, this can be a human–machine interface. The vital signs and molecular information collected using this platform could be used to design and optimize next-generation prosthetics." [Caltech story]
