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.
