Bioinspired Bimodal Mechanosensors with Real-Time, Visualized Information Display for Intelligent Control

Xiaoyan Qiu,Jize Liu,Bo Zhou,Xinxing Zhang

Imitating mechano-sensing luminescence of organisms has long been envisaged to achieve dynamic and real-time visualized information display, however, it remains challenging to recreate the skin-like visual sensation functions in artificial sensors. Here, a bioinspired mechanosensor is presented with mechanoluminescent/triboelectric hierarchical structure that is capable of pressure perception and patterning display in real time. Interestingly, a facilitative effect of interfacial triboelectric field on luminescent output and pressure visualization was found. The developed mechanosensor shows self-powered, bimodal, and real-time patterning sensation behavior with a low force detection limit (0.082 N), high sensitivity (9.69 a.u. N −1 ), fast response (35 ms), and good reliability (5000 cycles). On this basis, an intelligent control system is further constructed via combining image machine learning approach. This study not only addresses the long-lasting challenge of real-time pressure visualized display, but also boosts the further development of untethered, small-scale, and efficient intelligent systems.
