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.
