Abstract
An electrode system for the measurement of biopotential signals includes a substrate. A microelectrode is coupled to the substrate. An accelerometer is coupled to the substrate. A biopotential amplifier is electrically coupled to the microelectrode and acceleration measurement circuit is electrically coupled to the accelerometer. A method of measuring a biopotential from a patient includes sensing a biopotential with a microelectrode. The biopotential is amplified with an amplifier in electrical communication with the microelectrode. A movement of the electrode is sensed with an accelerometer integrated with the electrode substrate. The sensed biopotential and the sensed movement are provided to an electronic controller. Portions of the sensed biopotential that correspond to sensed movement are identified as artifact contaminated portions.
