摘要:
An electrode assembly that includes an electrically conductive layer, a first impedance reduction system, and a second impedance reduction system. The electrically conductive layer forms an electrode portion of the electrode assembly and a first surface to be placed adjacent a person's skin. The first impedance reduction system is configured to dispense a first amount of an electrically conductive gel onto the first surface of the electrically conductive layer in response to a first activation signal. The second impedance reduction system is configured to dispense a second amount of the electrically conductive gel onto the first surface of the electrically conductive layer in response to a second activation signal.
