Abstract

Anemotaxis behaviors inspired by rats have tremendous potential in efficiently processing perilous search and rescue operations in the physical world, but there is still lack of hardware components that can efficiently sense, encode, and recognize wind signal. Here, we report an artificial vibrissal system consisting of a self-powered carbon black sensor and threshold-switching HfO₂ memristor. By integrating a forming HfO₂ memristor with a self-powered angle-detecting hydro-voltaic sensor, the spiking sensory neuron can synchronously perceive and encode wind, humidity, and temperature signals into spikes with different frequencies. Furthermore, to validate the self-powered artificial vibrissal system with anemotaxis behavior, a robotic car with equipped artificial vibrissal system tracks trajectory toward the air source has been demonstrated. This design not only addresses the high energy consumption and low computing issues of traditional sensory system but also introduces the multimode functionalities, therefore promoting the construction of neuromorphic perception systems for neurorobotics.

具有趋风特性的自供电人工振动系统

受老鼠启发的趋风行为在有效处理现实世界中的危险搜救行动方面具有巨大的潜力，但目前还缺乏能够有效感知、编码和识别风信号的硬件组件。在这里，我们报告了一个由自供电的炭黑传感器和阈值开关HfO2记忆电阻器组成的人工振动系统。通过将形成型HfO2忆阻器与自供电角度检测水电传感器集成在一起，峰值感觉神经元可以同步感知风、湿度和温度信号并将其编码为不同频率的峰值。此外，为了验证具有厌风性的自供电人工振动系统，还演示了一辆配备人工振动系统的机器人汽车向气源跟踪的轨迹。该设计不仅解决了传统感官系统能耗高、计算量少的问题，而且引入了多模式功能，从而促进了神经机器人神经形态感知系统的构建。
