Figure 1. (A) Schematic diagram of the preparation of flexible self-powered E-skin based on MXene and its humidity sensing mechanism; (B) Application scenarios of the dual-functional E-skin integrating electrochemical energy storage and humidity sensing: non-contact ambient humidity monitoring and epidermal moisture perception. Post-use disposal requires no recycling, leaving no environmental pollution. Some image elements designed by Freepik (https://www.freepik.com/). E-skin: Electronic skin; MSCs: micro-supercapacitors.
