A biomimetic nociceptor system with tactile perception based on Ni-Al layered double hydroxides/gelatin heterojunction memristor

•The electronic simulation of the from pressure stimuli to nociceptors was conducted.•A bionic sensory system has been developed to present tactile perception.•The piezoelectric film sensor serves as an electronic skin.•The NiAl-LDHs/gelatin heterojunction memristor emulates biological nociceptors.•The essential characteristics of nociceptors, including threshold, no adaptation, relaxation, and sensitization were demonstrated.
