Nerve synapse bionic device based on polymer electrolyte double-layer structure

Abstract

The invention discloses a nerve synapse bionic device based on a polymer electrolyte double-layer structure. The bionic device comprises a lower electrode layer, a double-layer structure film and an upper electrode layer, wherein the double-layer structure film is formed by a positive charge polymer electrolyte layer which is prepared on the lower electrode layer and has a positive charge group on a main chain, a negative charge polymer electrolyte layer which is arranged above the double-layer structure film and has a negative charge group on a main chain, and the upper electrode layer is arranged above the double-layer structure film; the lower electrode layer comprises a substrate and a first electrode layer located above the substrate; the upper electrode layer is a second electrode layer; and the positive and negative charge polymer electrolyte films are prepared by adopting a spin-coating method. The nerve synapse bionic device has the advantages that the preparation method is simple and rapid, the used materials are low in price and free of pollution, the nerve synapse bionic device can be prepared on a flexible substrate and can also be prepared into a transparent device, the nerve synapse function can be efficiently simulated, and the nerve synapse bionic device has plasticity and the like.

Description

technical field [0001] The invention relates to the technical field of synaptic bionic devices, in particular to a neurosynaptic bionic device based on a polymer electrolyte double-layer structure. Background technique [0002] Due to the influence of the working efficiency of the human brain, the synapse simulation, which is the first important stage of the physical level of the brain work, has received more and more attention. Synapse is an important part of contact and transmission of information between neurons. The learning and memory functions of biological systems are based on the precise control of ion flow between neurons and synapses. The binding of neurotransmitter to the receptor on the posterior membrane changes the conformation of the receptor, causing a corresponding change in the postsynaptic membrane potential, and the presynaptic neuron transmits the change to the postsynaptic neuron to produce excitation or inhibition. Under the stimulation of a certain ...
