Abstract

The present invention relates to a bio-electrode having improved conductivity, flexibility and bio-compatibility, and a method of manufacturing the same. Specifically, the present invention relates to a conductive polymer bio-electrode including nano-porous permeable membrane, based on a bio-compatible polymer material having a plurality of pores and an improved surface area based on a PDMS device having a low mechanical strength and an excellent bio-compatibility, bio-signal transmission patterning, and a gold coating layer and has an excellent bio-compatibility and low rejection response while having a conductivity similar to that of a bio-electrode configured with a metal material of the related art. Therefore, the conductive polymer bio-electrode of the present invention is expected to be able to replace a bio-electrode configured with a metal material by which the bio-signal transmission efficiency is degraded due to a high bio-incompatibility.
