Sponge electrode
First Claim
1. An electrode providing electrical contact with a patient'"'"'s skin, said electrode comprising:
- a conductive member including means for connection to an external electrical apparatus; and
multilayer means for providing electrical interface between the patient'"'"'s skin and said conductive member, said multilayer means including first layer means, comprising an electrically conductive gel having a relatively low peel strength, for removably contacting the patient'"'"'s skin and second layer means, comprising an electrically conductive gel having a relatively high peel strength, for contacting said conductive member, the first and second layers being laminated with a sponge third layer therebetween.

Abstract
An electrode providing electrical contact with a patient'"'"'s skin includes a conductive member adapted for connection to an external electrical apparatus, and a multilayer system for providing electrical interface between the patient'"'"'s skin and the conductive member. The multilayer system includes a first layer of an electrically conductive gel having a relatively low peel strength, for removably contacting the patient'"'"'s skin, and a second layer of an electrically conductive gel having a relatively high peel strength, for contacting said conductive member. The first and second layers are laminated with a sponge third layer therebetween.
