In article number 1803961 , a ferroelectric/electrochemical modulated synapse is developed as a neuromorphic readout element for an artificial visual‐perception system, as presented by Yunlong Guo, Wenping Hu, Yunqi Liu, and co‐workers. Through electrochemical doping and ferroelectric switching, the synapse produces three types of synaptic plasticity, featuring postsynaptic signals with different retention times. Based on this synapse, a light‐triggered organic neuromorphic device that distinguishes colors is obtained, converting optical signals into short‐ and long‐term memory.
