Abstract

A dry gel-conductive sensor. In embodiments, the sensor comprises a scaffold structure which comprises a structure and a covering. A conductive material, which is both ionically and electronically conductive, may be dispersed within the structure. According to an embodiment, the covering comprises openings which allow conductive material through the covering to contact the skin of a subject. The covering may additionally or alternatively comprise brush-like features configured to penetrate through hair.
