摘      要：Despite recent remarkable progress in multiple synaptic devices,searching for artificial synapses with new functions is still an important task in the construction of artificial neural *** parallel output functionality of photoelectric signals in artificial synaptic devices is interesting and desirable as on-chip optoelectronic interconnection technology allows the connections between neurons weighted by current and *** turn,it provides degrees of freedom and reduces circuit lead density in the design of large-scale neural ***,for the first time,a light-emitting electrochemical artificial synapse(LEEAS)based on poly[2-methoxy-5-(2 -ethylhexyloxy)-1,4-phenylenevinylene]/poly(ethylene oxide)/lithium salt blends with dual output of photoelectric signals was developed in this *** electrochemical redox reaction enables the device to achieve synaptic plasticity in biology and emulate the memory enhancement process,high-pass filtering characteristic,and classical Pavlov’s conditioned reflex *** addition,the transient luminescence intensity of the LEEAS induced by identical electric spikes exhibits a synaptic-like potentiation *** to the combination of electroluminescence(EL)and synaptic memory behavior,an LEEAS array exhibits a unique image display and storage functions that can memorize displayed *** LEEAS proposed in this work enriches the diversity of artificial synapses,promoting the diversified design and development of next-generation optoelectronic hybrid artificial neural networks.
