Smart Electronic Skin for Robots and Prosthetics

Humans use the sense of touch to accomplish almost every daily task such as picking up a cup of coffee or shaking someone’s hand. Without it, humans can even lose their sense of balance when walking. Similarly, robots need to have a sense of touch in order to interact better with humans but...
