Recent progress of organic artificial synapses in biomimetic sensory neural systems

Abstract

The development of neuromorphic systems that emulate the brain's capabilities of learning, memory and pattern recognition has garnered significant interest in recent years. Developing artificial flexible synapses with low power consumption and high-density integration is crucial to realize high-efficiency neuromorphic sensory systems. Organic synaptic devices have emerged as promising candidates for artificial brain systems due to their simple structures, low fabrication costs, and minimal energy consumption compared to traditional Von Neumann architectures. Recent research studies have concentrated on adding organic synapses to brain-like systems to mimic the functioning of biomimetic sensory and motor nervous systems. Light, pressure, and other stimulus-triggered-organic synapses have been integrated with external sensors to mimic somatosensory, visual, auditory, gustatory and olfactory neural pathways, and have even formed sensory nervous systems. In this review, we summarize the recent progress of organic artificial synapses and biomimetic sensory neural systems. Furthermore, the current challenges and development prospects in biomimetic sensory neural systems were also outlined.
