Abstract
A touch sensor is provided that includes a transparent, insulating substrate and at least one U-shaped electrically conductive micromesh that includes traces disposed on the substrate. The traces include an elemental metal or an alloy of elemental metal. The touch sensor may be configured to determine a location and a magnitude of a force of a touch.
Claims20
A touch sensor comprising:
- a transparent, insulating substrate;
- and
- at least one U-shaped electrically conductive micromesh comprising traces disposed on the substrate, each micromesh in the at least one U-shaped electrically conductive micromesh having a uniform and periodic mesh pattern throughout the U-shaped micromesh, the traces comprising an elemental metal or an alloy of elemental metal.
A touch sensor comprising:
- a transparent, insulating substrate;
- at least one U-shaped electrically conductive micromesh comprising traces disposed on the substrate, each micromesh in the at least one U-shaped electrically conductive micromesh having a uniform and periodic mesh pattern, the traces comprising an elemental metal or an alloy of elemental metal;
- and
- electronics configured to measure a resistance for current passing through the at least one U-shaped electrically conductive micromesh and determine therefrom a location and a magnitude of a force of a touch.

An article comprising an electronic display and a touch sensor disposed upon the display, the touch sensor comprising:
- a transparent, insulating substrate;
- and
- at least one U-shaped electrically conductive micromesh comprising traces disposed on the substrate, each micromesh in the at least one U-shaped electrically conductive micromesh having a uniform and periodic mesh pattern, the traces comprising an elemental metal or an alloy of elemental metal,
- wherein the at least one U-shaped electrically conductive micromesh overlays at least a portion of a viewable region of the display without substantially obscuring the viewable region of the display, wherein the at least one U-shaped electrically conductive micromesh comprises at least one force sensing element, and wherein the touch sensor further comprises a separate positional touch-sensing element overlaying at least a portion of the viewable region of the display.
