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 third gel therebetween.

Abstract
An electrode provides electrical contact with a patient'"'"'s skin with the electrode including a conductive member for connection to an external electrical apparatus and multilayers of gel for providing electrical interface between the patient'"'"'s skin and the conductive member. A first layer is provided which includes an electrically conductive gel having a relatively low peel strength for removably contacting the patient'"'"'s skin and a second layer is provided which includes an electrically conductive gel having a relatively high peel strength for contacting the conductive member. The first and second layers are laminated in accordance with the method of the invention. Other layers may be utilized in combination with the first and second layers. Such layers include a scrim layer and a layer including physiologically active ions. Further, the electrode through the use of multilayer gels is suitable for use with garments for the selective positioning of electrodes to a patient'"'"'s skin.
