Abstract
A proto microelectrode from which a micro electrode is formed in situ upon insertion into soft tissue comprises a flexible oblong electrode body of electrically conducting material having a front end and a rear end. The electrode body having a metal or a metal alloy or an electrically conducting form of carbon or an electrically conducting polymer or a combination thereof. A first coat of a water soluble and/or swellable and/or degradable material is disposed on the electrode body and extends along is at least over a distal portion thereof. A second coat of electrically insulating, water insoluble flexible polymer material is disposed on the first coat. The second coat comprises one or more through openings at or near its front end. Also disclosed is a corresponding micro electrode and a method of manufacture.
