Abstract:
1. A touch sensor comprising: a first substrate comprising a plurality of electrodes formed on a surface of the first substrate; a second substrate comprising a plurality of electrodes formed on a surface of the second substrate, the surface of the second substrate comprising the plurality of electrodes opposing the surface of the first substrate comprising the plurality of electrodes, respective portions of the first and second substrates spaced being apart from each other by a dielectric material disposed between the respective portions of the first and second substrates, the plurality of electrodes forming of the first substrate each configured to form a capacitively coupled node with at least one of the plurality of electrodes of the second substrate, each capacitively coupled node configured to sense touch of an object, a portion of the second substrate deformed by compression such that a conductive pad on the second substrate and a conductive pad on the first substrate are connected and electrically coupled to each other wherein the portion of the second substrate is deformed by compression such that the conductive pad on the second substrate and the conductive pad on the first substrate are directly touching and galvanically coupled to each other; a solidified resin that had been injected in a liquid form on the second substrate, the conductive pad on the second substrate being compressed against the conductive pad on the first substrate by the injection of the resin while in the liquid form.
