Design and evaluation of a non-contact wireless biopotential monitoring system with motion artifacts

In this paper, we report the design and validation of a non-contact system for biopotential monitoring. The system is featured completely non-contact which can detect potential signals through cloth as thick as three layer jeans. The performance is comparable to the wet electrodes. In addition, we evaluate the motion artifacts of the non-contact electrodes under different textile materials and type of motions, which is one of the most significant barriers for wearable biopotential measurement. This study aims to pave the road for universal stable wearable non-contact biopotential detection.
