Skin ‐Inspired Textile Electronics Enable Ultrasensitive Pressure Sensing

A skin-inspired, flexible, breathable, and highly-sensitive textile-based pressure sensor is fabricated via a facile screen-printing and bionic microengineering strategy. This bionic textile-based sensor demonstrates excellent pressure sensing performance benefiting from the bionic intermittent structure. The sensor can also detect a wide range of human motion, and recognize pressure distribution via the electronic skin fabricated by sensor arrays. AbstractWearable pressure sensors have attracted great interest due to their potential applications in healthcare monitoring and human-machine interaction. However, it is still a critical challenge to simultaneously achieve high sensitivity, low detection limit, fast response, and outstanding breathability for wearable electronics due to the difficulty in constructing microstructure on a porous substrate. Inspired by the spinosum microstructure of human skin for highly-sensitive tactile perception, a biomimetic flexible pressure sensor is designed and fabricated by assembling MXene-based sensing electrode and MXene-based interdigitated electrode. The product biomimetic sensor exhibits good flexibility and suitable air permeability (165.6  mm s−1), comparable to the typical air permeable garments. Benefiting from the two-stage amplification effect of the bionic intermittent structure, the product bionic sensor exhibits an ultrahigh sensitivity (1368.9  kPa−1), ultrafast response (20  ms), low detection limit (1 Pa), and hig...
