BIOMEDICAL ELECTRODE PROVIDED WITH TWO-PHASE COMPOSITES CONDUCTIVE, PRESSURE-SENSITIVE ADHESIVE

摘要

A two-phase composite of ionically-conductive pressure-sensitive adhesive (14, 36), biomedical electrodes (10, 30) using the composite and methods of preparing the composite and the electrode are disclosed. The continuous phase is a hydrophilic, solid state pressure-sensitive adhesive composition ionically-conductive regardless of an amount of water present in the composition. The discontinuous phase are domains of a hydrophilic pressure-sensitive adhesive which enhances adhesion of the composite to mammalian skin while maintaining acceptable alternating current impedance of the composite.
