Abstract: A method of manufacturing a skin-compatible electrode (100) comprises printing a circuit pattern (P1) onto a flexible substrate (200) to form an electrically conductive pattern including an electrode pad area (301). A layer of an adhesive composition (401p) is printed in a second pattern (P2) onto the electrode pad area (301) to form an adhesive interface layer (401). The adhesive interface layer (401) is a dry film formed from the adhesive composition (401p) comprising an ionically conductive pressure sensitive adhesive composition comprising a resin (R), an ionic liquid (I), and optionally electrically conductive particles (P). A layer thickness and material of the flexible substrate, the conductive pattern, and the conductive adhesive interface have relatively low stiffness in plane of the flexible substrate (200).

Abstract: The present invention relates to an ionically conductive pressure sensitive adhesive composition useful as an electrode adhesive, which is an ionically conductive (meth)acrylate based pressure sensitive adhesive allowing prolonged biosignal monitoring times without skin irritation and loss of signal quality.

Abstract: The present invention relates to an electrode comprising a conductive pressure sensitive adhesive layer and a conductive layer. Furthermore, the invention refers to a method of manufacturing the electrode and to the use of the electrode for monitoring biosignals.
