Abstract：
Artificial electronic skin (e-skin), a network of mechanically flexible sensors which can wrap irregular surfaces conformally and quantify various stimuli sensitively, is potentially useful in healthcare monitoring and human-machine interaction (HMI). Although various approaches have mimicked the structures and functions of the human skin, challenges remain with high-density integration, super sensitivity, and multi-functionality. A multimodal and comfortable skin-inspired active-matrix circuitry is reported here with high pixel density based on all 2D materials, which can detect both mechanical interactions and humidity variations. The ultra-high sensitivity, long-term stability, and rapid response time for every pixel can fulfill simultaneous multi-stimulus sensing. Accordingly, a respiratory monitor is constructed to realize healthcare monitoring through observing the human breath frequency, intensity, and humidity in real-time. Moreover, the multimodal e-skin breaks through shackles of the contact sensor medium for HMI. 3D strain and humidity spatial mapping can reflect object location information even without contact, avoiding cross-infection of viruses effectively between users during the COVID-19 pandemic.
