Recent Advances in Flexible Organic Synaptic Transistors

Abstract In recent years, flexible organic synaptic transistors have attracted considerable attention due to their flexibility, biocompatibility, easy processability, and reduced complexity. Flexible organic synaptic transistors have functions and structures similar to biological synapses but have lower energy consumption. Therefore, they are widely used in mimicking neuromorphic functions. Such devices show significant prospects in the fields of electronic skin, artificial vision system, human brain interface, and wearable consumer electronics. This review summarizes the latest research progress of flexible organic synaptic transistor devices and discusses the selection of flexible substrates, device preparation technology, working mechanisms, and functions. Furthermore, the problems faced by flexible organic synaptic transistor devices and their potential applications are analyzed. This review provides a reference for the design and preparation of flexible organic synaptic transistor devices.
