摘要
目的基于tACS-EEG实验平台，研制用于研究和分析运动想象康复疗法的一种定制的多参数可调经颅电刺激器。方法选用低功耗芯片MSP430FR5739作为主MCU，再加上相关精确的辅助芯片，能够高速的、精确地控制刺激器的输出波形和电流，从而达到经颅交流刺激器的设计要求。结果通过输出波形和电流的重复验证和计算，研制的多参数可调经颅交流刺激器符合设计要求和设计原则。结论该多参数可调经颅交流刺激器各项指标和参数，和主流的经颅电刺激器基本一样。同时，其便携性和智能化的特征使得其能够更好地满足后续的研究和实验。
Objective To develop a kind of customized multi-parameters adjustable transcranial alternating stimulator to perform research and analysis on motor imagery rehabilitation therapy based on experiment platform of tACS-EEG.Methods Low power chip(MSP430FR5739)was used to be host MCU,and some related accurately auxiliary chips were added to control the output waveform and current of stimulator high-speedily and accurately.In this case,the designed requirement of transcranial alternating stimulator could be reached.Results According to repeatability verification and calculation,the multi-parameters adjustable transcranial alternating stimulator was accorded with design requirement and principle.Conclusion Various indexes and parameters of the multi-parameters adjustable transcranial alternating stimulator were essentially the same as the mainstream TCS.Meanwhile,its portability and intelligence characteristics make it satisfy the subsequent study and experiment better.
