Abstract

This paper will present ongoing work in the development of a thin, flexible, photolithographically-defined polymer-based electrode array based on Liquid Crystal Polymer (LCP) films and substrates. The goal of the effort is to develop and qualify a new platform technology that would allow accurate positioning of large numbers of electrode contacts in neural tissue for chronic applications. LCP films are a far greater match to the density of neural tissue than the competing wire and silicon arrays and thus will match the bending and flexing as the neural tissues change dimension. This flexibility would cause less neural damage and will maintain a more constant relationship with local neurons. Technology development activities include thin film metallization, interconnect insulation and device microfabrication.
