Attorney, Agent or FirmAbstractA tape form electrode is provided which is usable for transmission of electrical signals into the human body through the skin. The electrode is of a construction so that it can be applied to the skin to secure good electrical contact therewith and remain in place for many days despite normal movement and the normal activities of the subject such as perspiring, and washing. The construction utilizes a porous backing material which has an adhesive layer on one side thereof and over the adhesive layer a second layer which has incorporate therein a quantity of finely divided silver metal. The composition construction is of a thickness and selection of materials such that it readily "breaths" thereby permitting escape of normal amounts of perspiration from the skin of the subject. The adhesive is normally "dry" and is activated at the time of application by a suitable solvent. | |
