Abstract

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 (>100 cm –2 ) based on all 2D materials, which exhibits excellent performance to detect both mechanical interactions and humidity variations. The ultra‐high sensitivity (>400 and ≈ 10 4 for strain and humidity sensing, respectively), long‐term stability (>1000 cycles), 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. The reported e‐skin will broaden applications for future healthcare and human–machine interactive devices.

In particular, the contactless modal breaks through the shackles of a contact sensor medium for traditional human–machine interaction.
