Abstract

A conductive element (3) which can serve as capacitive sensing element comprises a conductive pad (9) comprising relatively low conductivity material, such as carbon- based ink, and a conductive mesh (10) comprising relatively high conductivity material, such as silver-based ink, underlying or overlying the pad to form a composite conductive element. A conductive element (5) which can serve as a connector to a capacitive sensing element comprises a set of elongate conductive tracks (13) and a set of conductive members (14) crossing said tracks.
