Abstract
A conductive element which can serve as capacitive sensing element comprises a conductive pad comprising relatively low conductivity material, such as carbon-based ink, and a conductive mesh comprising relatively high conductivity material, such as silver-based ink, underlying or overlying the pad to form a composite conductive element.
Claims32
A printed article comprising:
- a substrate;
- and
- at least one capacitive touch switch supported on the substrate;
- wherein each capacitive touch switch comprises:
- a conductive pad comprising relatively low conductivity material;
- and
- a conductive mesh comprising relatively high conductivity material underlying or overlying the pad and being in contact with the pad so as to form a composite conductive element,
- wherein the conductive mesh includes open areas without the relatively high conductivity material, each open area being a least 20 mm2.
