In order to prepare a flexible dry-type electrode for electrocadiogram (ECG), conductive poly(vinylidene fluoride) [PVDF] was electrospun and silver-plated electrolessly. The surface morphology and the mechanical and electrical properties of the silver-plated nanowebs prepared under different plating conditions were evaluated. After silverplating, the prepared web was welded ultrasonically in order to improve the conductivity and the rubbing fastness. Drytype electrodes were fabricated into eyelet shape by using the ultrasonically welded silver-plated PVDF nanoweb, a sponge and a metal eyelet. Then, it was attached to a commercial sports brassiere top. The ECG of the wearer of the top was measured by the newly developed electrodes and the commercial Ag/AgCl gel electrodes while walking and running. The comparison reveals that the silver-plated PVDF nanowebs can be used as an electrode for ECG measurement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
