The invention relates to a stretching-
pain perception system based on a multi-gate synaptic
transistor and a preparation method and application thereof, and belongs to the technical field of artificial
sensory neuron and neuromorphic calculation. The
system comprises a crack type
strain sensor and a multi-gate synaptic
transistor, the
strain sensor adopts a
metal / elastic
composite material double-layer conductive structure, and has high sensitivity and a continuous conductive path; the multi-gate synaptic
transistor takes an
electrolyte material as a gate medium, takes a
metal oxide as an
electrode and a channel, and is provided with a
bottom gate and a side gate. The
strain sensor is connected with the bottom grid and the side grid through a
voltage division circuit, and dynamic integration and
processing of stretching signals are achieved by regulating and controlling different grid voltages. According to the invention, multi-stage mode conversion from conventional stretching
perception to pain early warning is realized, the method is suitable for biological nerve
simulation systems such as
electronic skin, intelligent
artificial limbs and bionic robots, and the
bottleneck problem that an existing
pain perception system is difficult to realize multi-
signal fusion and dynamic regulation and control is solved.
