Neuromorphic engineering aims to build artificial bionic nervous systems on hardware to emulate the unique and efficient operating mechanism of the brain,implementing neuromorphic perception and brain-inspired computing.Synapses are the basic structure and functional units of learning and memory.Therefore,the construction of synapses-like electronic devices is the key to achieving neuromorphic perception and computing.Three-terminal transistor devices have advantages in realizing multi-state regulation and reducing energy consumption.In addition,the three-terminal transistor can also convert external physical stimuli such as pressure and temperature into electrical signals.It has a broad application prospect in the artificial sensory nervous system,which collects visual,auditory and olfactory signals to work.In this paper,material selection and the device structure of three-terminal synaptic transistors are reviewed,and the recent progress in artificial vision,hearing and smell perception systems based on the three-terminal synaptic transistor is introduced.Finally,we summarizes the challenges faced by the three-terminal synaptic transistor and its associated artificial sensing system while also providing a glimpse into the prospects for its future development.
