ACTIVE, MULTIPLEXED DIGITAL ELECTRODES FOR EEG, ECG AND EMG APPLICATIONS

摘要

A biopotential measurement system incorporates a revolutionary approach to the acquisition of signals such as Electroencephalograms (EEG), Electrocardiograms (ECG), and Electromyograms (EMG) by incorporating active, digital electrodes that amplify and digitally convert biopotential signals at the source, thereby eliminating noise and signal degradation issues. This is to date the most integrated and advanced electrode designed for any biopotential measurement eliminating the poor Signal-to-Noise (SNR) problems seen in biopotential recordings. The digitized signals are then multiplexed across an electromagnetic two-way communication channel to a remote controller that selects which electrode to sample.
