Embodiment 1

[0055] This embodiment provides an artificial sensory neural circuit, figure 1 is a schematic diagram of the circuit structure of the artificial sensory nerve circuit, and the artificial sensory nerve circuit includes a sensor S, a first memristor RS and a neuron circuit.

[0056] Specifically, the sensor S is used for sensing external signals and generating an excitation signal according to the external signals. The sensor S can be a photoelectric sensor, a pressure sensor, etc., and the type of the sensor S can be determined according to actual application scenarios. The first memristor RS is used to generate a response signal according to the excitation signal. In this embodiment, the first memristor RS has a unidirectional resistance-switching characteristic. The unidirectional resistive switching characteristic is also called unipolar resistive switching behavior, which means that the resistive switching behavior does not depend on the polarity of the applied voltage.

Description

technical field [0001] The invention relates to the technical field of bionic electronics, in particular to an artificial sensory nerve circuit and a preparation method thereof. Background technique [0002] The sensory nervous system is an important channel for organisms to perceive external information, so the artificial sensory neural circuit has a wide range of application scenarios, for example, it can be applied in the fields of intelligent robots, prosthetics, and artificial skin. Non-associative learning is a form of learning that does not form a clear connection between stimulus and response, and is presented repeatedly by a single pattern of stimuli, correspondingly causing a learning process that stimulates changes in a single sensory system in the brain. Sensitive and habitual characteristics are typical non-associative learning modes. At present, the circuit structure based on traditional CMOS circuits to realize sensitive and habitual characteristics is complic...
