The first stretchable energy?harvesting electronic?skin device capable of differentiating and generating energy from various mechanical stimuli, such as normal pressure, lateral strain, bending, and vibration, is presented. A pressure sensitivity of 0.7 kPa?1 is achieved in the pressure region <1 kPa with power generation of tens of μW cm?2 from a gentle finger touch.
