Bio-electrode and method for manufacturing bio-electrode

Abstract

The present invention is a bio-electrode includes an electro-conductive polymer composite layer, an electro-conductive layer (C), and a substrate (D). The electro-conductive polymer composite layer consists of an electro-conductive polymer composite which includes (A) a π-conjugated polymer and (B) a dopant polymer. The substrate (D) has a transmittance of 20% or more at a wavelength of 600 nm and is yellow-red (YR) with a value in the range of 1 to 9 and a chroma in the range of 1 to 12 in the Munsell color system. This provides: a bioelectrode which is thin film, highly transparent, slightly different from the skin in color, highly sensitive to biological signals, excellent in biocompatibility, light-weight, manufacturable at low cost, capable of preventing significant reduction in the sensitivity to biological signals when wetted with water or dried and when attached on the skin for a long time; and a method for manufacturing the bio-electrode.
