摘要：

Smart sensors are expected to be sustainable, stretchable, biocomfortable, and tactile over time, either in terms of mechanical performance, reconfigurability, or energy supply. Here, a biocompatible piezoelectric electronic skin (PENG) is demonstrated on the base of PZT-SEBS (lead zirconate titanate and styrene ethylene butylene styrene) composite elastomer. The highly elastic (with an elasticity of about 950%) PENG can not only harvest mechanical energy from ambient environment, but also show low toxicity and excellent sensing performance toward multiple external stimuli. The synchronous and independent sensing performance toward motion capture, temperature, voice identification, and especially the dual-dimensional force perception promotes its wide application in physiological, sound restoration, and other intelligent systems.
