A heterogeneous, pressure-sensitive, electrically conductive adhesive for disposable biomedical electrodes. The adhesive consists of two phases: a viscoelastic polymeric adhesive phase and an electrically conductive aqueous phase containing a water receptive polymer, a humectant, and an electrolyte. Both phases are intimately interdispersed and the adhesive is applied as a relatively thin film on a supporting substrate. The adhesive is characterized in that it establishes a physical equilibrium with the ambient system so that varying concentrations of moisture in the atmosphere are accommodated and tolerated by the adhesive without loss of viscoelastic and adhesion capabilities and without impairment of electrical conductivity values even under conditions of both high and of low relative humidity.

Pressure sensitive adhesive compositions for medical electrodes

A disposable biomedical and diagnostic electrode characterized in that functional electrical contact is effected between the skin and an electrically conductive element of the electrode by means of a conductive adhesive, and in that conductive skin contact is enhanced, when necessary, by selective application of a conductive gel contained in and releasable from a storage cavity in the electrode itself. The pressure-released gel establishes a fluid film interface between the patient's skin and the conductive adhesive and, concurrently, provides a highly conductive path between the electrode itself, and the patient's skin.

Disposable biomedical and diagnostic electrode

A membrane for electrochemical analysis is described comprising a first, relatively dense and thin layer and a second, relatively porous thick layer, which thick layer has dispersed therethrough the enzyme, glucose oxidase. The process of making the membrane by casting two to three layers of cellulose acetate compositions is also described.
