An energy-efficient tactile-sensing element composed of a triboelectric nanogenerator (TENG) and an electrolyte-gated synaptic transistor (EGT) is presented for biological tactile sensory neuron emulation. As the mechanoreceptor, TENG converts pressure signals into voltage pulses directly. The EGT is used as a neuromorphic device to emulate the behaviors of biological synapse. Typical functions of tactile sensory neuron to perceive dynamic pressures with different intensities, amounts and frequencies are studied. Besides, spiders’ ability of identifying prey by sensing the vibrations of cobweb is also emulated.

氧化物突触晶体管与摩擦纳米发电机相结合,用于仿生触觉传感应用

提出了一种由摩擦纳米发电机 (TENG) 和电解质门控突触晶体管 (EGT) 组成的节能触觉传感元件,用于生物触觉感觉神经元仿真。作为机械感受器,TENG 将压力信号直接转换为电压脉冲。EGT 被用作神经形态装置来模拟生物突触的行为。研究了触觉感觉神经元感知不同强度、数量和频率的动态压力的典型功能。此外,还模拟了蜘蛛通过感知蜘蛛网的振动来识别猎物的能力。
