我们提出了一种基于神经尖峰处理的生物启发触觉传感器阵列。异步数据处理与传感器阵列集成在片上，并将高带宽原始输入数据转换为带宽要求较低的高级信息。与传统的基于速率的神经脉冲代码不同，该阵列使用基于相位的计算原语，可以实时计算接触点、力大小、力方向以及是否存在滑动。仿真表明，与同类同步方法相比，计算量减少了多达三个数量级。
We propose a biologically inspired tactile sensor array based on neural spike processing. Asynchronous data processing is integrated on-chip with the sensor array and converts the high-bandwidth raw input data into higher-level information with lower bandwidth requirements. Using phase-based computation primitives, as opposed to traditional rate-based neural spike codes, the array can compute the point-of-contact, force magnitude, force direction, and the presence or absence of slips, all in real time. Simulations demonstrate a reduction in the number of computations by up to three orders of a magnitude over a comparable synchronous approach.
