在这项工作中，我们报告了一种新的电路架构，实现事件驱动的触觉传感使用POSFET触觉设备。所提出的电路匹配POSFET器件的优点（在同一管芯上集成感测和电子器件、高机电转换带宽等）。与事件驱动的方法相比较。在所提出的电路中，POSFET器件与集成和激发类型的尖峰神经元接口：输入的机械刺激被转换为数字脉冲。该方法为基于POSFET器件的神经形态集成触觉传感系统的实现铺平了道路。
In this work, we report a novel circuit architecture to implement event-driven tactile sensing using the POSFET tactile device. The proposed circuit matches advantages of the POSFET device (integration of sensing and electronics on the same die, high electromechanical transduction bandwidth, etc.) with the ones of the event-driven approach. In the proposed circuit, the POSFET device is interfaced with a spiking neuron, of the type integrate and fire: the input mechanical stimulus is translated into digital pulses. The proposed approach paves the way for the implementation of neuromorphic integrated tactile sensing systems based on POSFET devices.
