Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites
Advanced Materials Technologies, EarlyView.Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
