Abstract: Disclosed are an artificial sensory nervous circuit and a manufacturing method thereof. The artificial sensory nervous circuit includes a sensor (S), a first memristor (RS), and a neuron circuit, where the first memristor (RS) has a unidirectional resistance characteristic. The sensor (S) is configured to sensing an external signal and generating an excitation signal according to the external signal. The first memristor (RS) is configured to generating a response signal according to the excitation signal. The neuron circuit is configured to perform charging and discharging according to the response signal so as to output a pulse signal. With the artificial sensory nervous circuit and the manufacturing method thereof, sensitivity and habituation characteristics of biological perception are realized by using a simple circuit.

Abstract: A neuron circuit (100), including a memristive element (M1), a trigger element (D1), a feedback element (T1) and an AND circuit (A1). The memristive element (M1) is used to receive an excitation signal. The trigger element (D1) is connected to the memristive element (M1) and is used to receive a clock control signal for the neuron circuit and an output signal of the memristive element (M1). The feedback element (T1) is connected to an output end of the trigger element (D1) and an input end of the memristive element (M1) and is used to control a voltage at the input end of the memristive element (M1). The AND circuit (A1) is used to perform an AND operation on an output signal of the trigger element (D1) and the clock control signal. An output signal of the AND circuit (A1) acts as an output signal of the neuron circuit (100).
