In this paper, we present a novel event-driven Dynamic Tactile Sensor (DTS) for artificial devices. The sensor is based on the POSFET (Piezoelectric-Oxide-Semiconductor-Field-Effect-Transistor) as the tactile sensing device with the change detector (CD) circuit of the DVS (Dynamic Vision Sensor) [1] as a readout circuit. The sensor unit encodes the input pressure variation over time. Encoding of pressure levels recalls the skin Meissner Corpuscles based mechanoreceptors. We show a quantitative analysis that highlights the overall functionality through circuit simulation results. © 2017 IEEE.

Abstract
In this paper, we present a novel event-driven Dynamic Tactile Sensor (DTS) for artificial devices. The sensor is based on the POSFET (Piezoelectric-Oxide-Semiconductor-Field-Effect-Transistor) as the tactile sensing device with the change detector (CD) circuit of the DVS (Dynamic Vision Sensor) [1] as a readout circuit. The sensor unit encodes the input pressure variation over time. Encoding of pressure levels recalls the skin Meissner Corpuscles based mechanoreceptors. We show a quantitative analysis that highlights the overall functionality through circuit simulation results. © 2017 IEEE.
