Brain-inspired computing is generally considered to be a new computing paradigm that can achieve high computing power and low power consumption,and it is expected to break through the bottleneck of traditional von Neumann architecture.In recent years,inspired by the unique working mode of the human brain,the use of new devices to construct brain-like devices with in-memory computing functions has received considerable attention.The development of neural synaptic devices and systems with biological synaptic behaviors is of great significance for the development of ultra-low-power brain-like chips and the realization of neuromorphic sensing systems.Among these devices,organic electrochemical transistors(OECTs),as a new branch of artificial synapse research,have been extensively studied due to their higher transconductance,low driving voltage,good mechanical flexibility,and biocompatibility.Structurally,the OECTs channel is in direct contact with the electrolyte,and the channel conductance is regulated by ionic doping/de-doping,which is similar to the ionic driving process and dynamics of biological systems.Therefore,utilizing OECTs to develop multisensory and biocompatible brain-like biomimetic systems is a feasible solution.This article discusses the research progress of organic electrochemical brain-inspired bionic electronic devices and the current challenges and development trends in this field.
