Bio-electrode composition, bio-electrode, method for manufacturing bio-electrode, and silicon material particle

Abstract

A bio-electrode composition contains particles having surfaces with a sulfonimide salt shown by the following general formula (1). R1 represents a linear, branched, or cyclic alkylene group having 1 to 20 carbon atoms and optionally having an aromatic group, ether group, or ester group, or an arylene group having 6 to 10 carbon atoms. Rf represents a linear, branched, or cyclic alkyl group having 1 to 4 carbon atoms, or an aryl group having 6 to 10 carbon atoms, and optionally has a fluorine atom. M+ represents an ion selected from the group consisting of lithium, sodium, potassium, and silver ions. This invention provides a bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity and biocompatibility, light-weight, and manufacturable at low cost, and prevents significant reduction in electric conductivity even when wetted with water or dried.
