Stretchable Energy-Harvesting Tactile Electronic Skin Capable of Differentiating Multiple Mechanical Stimuli Modes

Abstract

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.
