Abstract: An apparatus, system, and method of reducing and controlling values of at least one characteristic (e.g., impedance) associated with biopotential-signal sensors is provided. The apparatus, system, and method includes monitoring—based on data from a wearable device that includes a biopotential-signal sensor, a characteristic-stabilizing component, and a characteristic monitor—a characteristic at the sensor-skin interface that impacts the biopotential-signal sensor's ability to sense biopotential signals. In accordance with selecting a biopotential-signal sensitivity need, provide an adjustment (e.g., stimulation) to the characteristic in accordance with a sensitivity-stabilizing mode until the characteristic satisfies the first biopotential-signal sensitivity need. The adjustments may be provided in various methods to achieve desired results.
