Electronic sensor skins is an active area of research for many groups over the world due to its potential to enable dramatic changes in how we interact with the digital environment. For example, ‘robots’ can don on sensor active skins to shake human hands with comfortable pressure, measure our health biometrics and possibly aid in wound healing. In my talk, I will discuss the development of electronic sensor skins with some historical context, followed by showcasing of several force sensitive electronic skin technologies with high sensitivity, stretchability and self-healing abilities1-3. More recently, inspired by human skin touch receptors, we demonstrated a power-efficient frequency encoded artificial mechano-receptor system4. We further used a channelrhodopsin with fast kinetics and large photocurrents as an optical interface to neuronal systems for next generation opto-tactile prosthetic interfaces.
