Abstract

A shielded microelectrode process and product wherein the microelectrode is coated by vacuum evaporation techniques with a thin layer of silver; the silver from the microelectrode tip region is removed to a depth of no greater than substantially 20 micrometers by contact with memory; and the microelectrode is dipped into a thermosetting wax in liquid form whereby as the wax solidifies the silver is coated thereby below the tip region.
