【摘要】 介绍一种用于研究生物体运动神经机理的在体拟生物信号电刺激装置。刺激器以DSP为计算核心,采用基于振动理论的神经元模型生成信号,输出模拟电压,通过微电极进行在体刺激。实验结果证实,刺激信号在形态上与生物信号基本吻合,并且刺激强度、频率等可调。此研究为后续研究生物机器人技术提供了硬件准备。更多还原

【Abstract】 This paper introduces an electrical stimulator used for researching on biology’s neurophysiology. The stimulator uses DSP as the computing core, based on vibration theory neuron model. It outputs the signals as the biology patterns, and through the micro-eletrode stimulate in vivo It is proved that the stimulus signal patterns are basically consistent with the biological signals. And these signals can be changed in pattern, amplitude, frequency, etc. This stimulator will be used in the hardware of bio-robot technology for the follow-up study.更多还原
