Abstract
Disclosed herein is an electrode for human heart pacemaker comprising an electrode substrate prepared by Pt or a Pt alloy, Ti or a Ti alloy and a mixture of platinum and a platinum group metal oxide coated thereon, the upper portion of the electrode being comprised of mesh or porous. Since the physical dimensions of the electrodes can be made smaller, the substantial surface area can be made larger and the catalytic performance can be elevated because of the coating on the electrode of the present invention. The electrode has remarkably low polarizability, a high response characteristic from a human heart, low electric consumption, smaller input impedanco and extremely high reliability. Also disclosed is an implantable mesh electrode comprising a Pt/Ti composite prepared by coating Ti with Pt.
