Abstract :
A wireless EEG/ECG system using non-contact sensors is presented. The system consists of a set of simple capacitive electrodes manufactured on a standard printed circuit board that can operate through fabric or other insulation. Each electrode provides 46 dB of gain over a .7-100 Hz bandwidth with a noise level of 3.80μV RMS for high quality brain and cardiac recordings. Signals are digitized directly on top of the electrode and transmitted in a digital serial daisy chain, minimizing the number of wires required on the body. A small wireless base unit transmits EEG/ECG telemetry to a computer for storage and processing.
