Advanced synaptic devices and their applications in biomimetic sensory neural system

Abstract

Human nervous system are consisted of neuron and synapse networks, and are capable to processes information in a plastic, data-parallel, fault-tolerant, and energy-efficient approach. Inspired by the ingenious working mechanism of this miraculous biological data processing system, scientists are devoting great efforts to artificial neural systems based on synaptic devices in recent decades. With the continuous development of bioinspired sensors and synaptic devices, artificial sensory neural systems that capture and process stimuli information in real time become possible. The progress of biomimetic sensory neural systems could provide new methods for next-generation humanoid robotics, human-machine interfaces, and other frontier applications. Herein, this review summarized the recent progress of synaptic devices and biomimetic sensory neural systems. Additionally, the opportunities and remaining challenges in the further development of biomimetic sensory neural systems are outlined.
