Abstract:

Brain-inspired neuromorphic engineering is becoming a hot topic in the field of information technology. It will be a strong supplement and growth point for artificial intelligence in the near future. And it will promote the development of microelectronics technology. Our brain has ~1011 neurons and ~1015 synapses. Synapses are the connections between neurons where signals will be transmitted. They are the basic units for cognitive behaviors. With a big amount of parallel synaptic computations, brain computation is very powerful and reliable. Thus, designing artificial synapses that could emulate essential synaptic plasticities is of great importance for hardware implementation of neuromorphic engineering. Presently, the studies of artificial synapse devices just started around the world. New research results continue to emerge. It is becoming an important branch of artificial intelligence and neuromorphic engineering and it will inject new vitality into the developments of artificial intelligences in the future. Ionic-conducting electrolytes possess unique interfacial ionic/electronic coupling effects. They have potential applications in the electrostatic modulation devices. Such devices provide new solutions for revealing new physics of condensed matter. Especially, such devices have strong potential applications in brain-inspired artificial synapse devices and neuromorphic systems because of the unique interfacial ionic coupling and the related interfacial electrochemical processes.
