Fingertip-inspired electronic skin based on triboelectric sliding sensing and porous piezoresistive pressure detection

A fingertip-inspired multifunctional electronic skin capable of detecting pressure and sliding movement simultaneously is developed based on the anatomical structure of human skin. Sliding sensing is detected by triboelectric effect while pressure sensing is detected by porous resistive material, corresponding to fast adapting (FA) and slow adapting (SA) in physiological functions, respectively, which greatly broaden its potential application fields.211
