Abstract
A method and apparatus for biopotential sensing and stimulation are provided including a sensory component, a biopotential sensor electrode, and a biopotential sensory electrode system. The sensory component includes a first layer of electrically conductive material coupled among a biopotential signal source and a dielectric layer. A second layer of electrically conductive material is coupled among the dielectric layer, resistive elements, a charge balancing current source and sink, and circuits of the associated biopotential electrode. The biopotential sensor electrode includes the sensory component, conditioning components, an interface, and a power source. Stimulation components may also be included to provide stimulation signals to the biopotential signal source. The interface transfers signals to external instrumentation using wireless or wired connections. The power source includes batteries, solar cells, and telemetry power sources. The biopotential sensory electrode system includes electrode arrays and a receiver section that transfers biopotential signals among the biopotential signal source and external instrumentation and equipment. A reference link among the sensor elec…
