A sensor for measuring biosignals is provided. The sensor comprises at least one electrode comprising: a substrate comprising a flexible non-conductive material; a conductive layer configured to transfer electrical signals; a gel layer configured to transfer electrical signals; and a barrier layer configured to protect the conductive layer and transfer electrical signals, wherein the barrier layer deposited on the substrate, the gel layer is deposited on the barrier layer so that the gel layer covers only a part of the barrier layer, and the conductive layer is deposited over an area of the barrier layer which is outside of an area of the barrier layer on which the gel layer is deposited.

Sensor for measuring biosignals

An electrode for obtaining a biopotential signal from the skin of a subject. The electrode comprises an adhesive element, an electrode body, an electrically conductive electrode pad, a sponge element, soaked with conductive gel, and means for skin abrasion. The means for skin abrasion comprises abrasion elements forming an integrated structure with the electrode pad, the abrasion elements being so dimensioned that the sponge element prevents the abrasion elements from touching the skin when biopotential signals are measured and enables mechanical contact between the skin and the abrasion elements when the electrode pad is pushed towards the skin. The electrode body is made flexible to enable intentional movement of the electrode pad relative to the adhesive element.
