Despite its widespread use in signal collection, flexible sensor has been rarely used in
human-machine interaction due to its indistinguishable signal, poor reliability and stability when suffered from unavoidable scratches and/or mechanical cuts. Here, we demonstrate a highly sensitive and self-healing sensor enabled by multiple hydrogen bonding network and nanostructured conductive network. The nanostructured supramolecular sensor displays extremely fast (~15 s) and repeatable selfhealing ability with high healing efficiency (93% after the 3rd healing process). It can precisely detect tiny human motions, demonstrating highly distinguishable and reliable signals even after cuttinghealing and bending over 20000 cycles. Furthermore, a human-machine interaction system is integrated to develop a facial expression control system and an electronic larynx, aiming to control the robot to assist the patient''''''''s daily life and help the dumb to realize real-time speaking.
