A non-woven fabric of rayon or the like as illustrated in the drawing provides an excellent absorbent carrier.

2, the hydrogel 14 is impregnated in and carried by the porous matrix 12 in the form of a fabric or pad, e.g., rayon, cotton, cellulose acetate, cheesecloth, plastic sponge or foam, so that a hydrogel surface is presented on both sides of the pad. 1 shows the general structure of a short term diagnostic gel pad designated by the number 10. Referring now to the drawings for a detailed consideration of the gel pad, FIG.

Similarly, an electrode employed in long term diagnostic use also requires an application of jelly or cream to the underside of the electrode to provide a conductive interface between the skin and electrode which necessitates cleanup. First, the individual applying the electrode to the patient must also apply the cream or jelly to the electrode and skin resulting in a residue on the hands of the technician and secondly, a messy residue remains on the skin of the patient and on the electrode after removal which necessitates cleanup of the patient and the electrodes, such cleanup usually requiring a soap or solvent wash after electrode removal from the skin. Although these creams and jellys adequately perform the function of a conductive interface between standard medical electrodes and the skin of a patient, the creams and jellys have two destinct disadvantages. In order to have uniform contact with the skin area, a jelly or cream from a jar or a tube is applied to the area of the device which is to come in contact with the skin. This type of 'noise' may substantially change the accuracy of a reading. A substantially uniform contact between the metal electrode and the skin is necessary to prevent 'electrical noise' due to minute spaces between the electrode and skin. There are many different types of electrical conducting devices which are presently being used in medicine, especially in electrocardiography and electroencephalography.
