This paper proposes and experimentally demonstrates an artificial spiking afferent nerve (ASAN) based on highly reliable NbOx Mott memristors. The spiking frequency of the ASAN is proportional to the stimuli intensity before encountering noxiously high stimuli, after which it reduces the spiking frequency. Using this ASAN, a power-free spiking mechanoreceptor system is built with a passive piezoelectric device as the tactile sensor. Experimental results suggest the ASAN is promising for self-aware neurorobotics.
