摘      要：An artificial withdrawal reflex arc that can realize neuromorphic tactile perception,neural coding,information processing,and real-time responses was fabricated at the device level without dependence on *** an extended application,the artificial reflex arc was used to perform an object-lifting task based on tactile commands,and it can easily lift a 200-g weight.A fiber-exploiting electro-optical synaptic transistor(FEST)was fabricated to emulate synaptic plasticity modulated by electrical or optical *** to an ultrahigh spike duration-dependent plasticity index(~12,651%),the FEST was applied in electro-optical encrypted communication tasks and effectively increased signal recognition *** addition,the FEST has excellent bending resistance(bending radii=0.6-1.4 cm,bending cycles2000)and stable illumination responses for a wide range of incident angles(0°-360°),demonstrating its potential applicability in wearable *** work presents new design strategies for complete artificial reflex arcs and wearable neuromorphic devices,which may have applications in bioinspired artificial intelligence,human-machine interaction,and neuroprosthetics.
