The synapse of human brain neurons is not only the transmission channel of information,but also the basic unit of human brain learning and information storing.The artificial synapse is constructed based on the Sr0.97Ba0.03TiO3-x(SBT) memristor,which realizes the short-term and long-term plasticity of the synapse.The experiential learning and non-associative learning behavior in accordance with human cognitive rules are realized by using the SBT-memristor-based synapse.The process of synaptic habituation and sensitization is analyzed.This study provides insightful guidance for realization of artificial synapse and the development of artificial neural network.
