英文摘要： On the basis of a comprehensive analysis of the current developing technologies in BCI research area and former researchers'design experences, according to the existing problems on neural signal acquisition and stimulation in the study of nerual information, this project provides a design idea and method to develop a kind of implantable wireless micro-device which can produce multi-channel stimulation and acquire neural signals with high speed within an integrated chip. It has features of total implantion, wireless powering and telemetry & telecontrol. Besides that, the wireless transmition and receiving technology adopted in this project is also compatible with the standards of the International Telecommunication Union (ITU). The microsystem developed here with the integration of stimulation and acquisition, and whose eletrodes can be configed flexibly has very great value for the study of neural information and the implementation of neuralprosthetic systems form the study of lab in to the practical clinic applications.
