Electrode with redundant impedance reduction
First Claim
1. An electrode assembly, comprising:
- an electrically conductive layer that forms an electrode portion of the electrode assembly, the electrically conductive layer having a first surface to be placed adjacent a person'"'"'s skin;
a first impedance reduction system configured to dispense a first amount of a first electrically conductive gel onto the first surface of the electrically conductive layer in response to a first activation signal; and
a second impedance reduction system, independently operable of the first impedance reduction system, configured to dispense a second amount of a second electrically conductive gel onto the first surface of the electrically conductive layer in response to a second activation signal that is distinct from the first activation signal.

Abstract
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.
