Wireless EEG-fNIRS Fusion Signal Acquisition System for Depth of Anesthesia Monitoring
摘要
Depth of anesthesia monitoring has been adopted in clinic in the recent years. However, misjudgments could occur under certain circumstances, which would harm patients mentally or even physically. In this article, we have proposed a novel hybrid EEG-fNIRS signal acquisition system with self-designed EEG and fNIRS acquisition modules. Results show that the EEG module has an indication error between 4 and 14%, the fNIRS module could drive laser sources and acquire signals with a 0.005 V converted signal resolution, and the system could acquire, visualize and save the data with a stable running time of about 1 h. The proposed system has huge potential for DoA monitoring.
