Research Update: Platinum-elastomer mesocomposite as neural electrode coating
Source abstract
Abstract
Platinum is electrochemically stable and biocompatible, and remains the preferred material for the fabrication of implantable neural electrodes. In a foil or film format, platinum is mechanically stiff compared to interfaced biological tissue. We report a soft, highly stable platinum-elastomer composite that offers both mechanical compliance and the electrochemical properties of platinum. We demonstrate the high-performance of the novel mesocomposite printed on stretchable microelectrodes both in vitro and in vivo. The platinum-elastomer composite is a new promising coating for chronic neural interfaces.
