Capacitive sensing devices are provided that include a sensing pattern of conductive traces disposed upon the surface of a substrate and a first passive circuit element that includes a metallic conductor disposed upon the same surface of the substrate. In some embodiments, the first passive circuit element is a component of an electronic circuit that can be, for example, a low pass filter. Provided capacitive sensing devices are useful, for example, when incorporated into projected touch screen display panels for use on electronic devices.

Integrated passive circuit elements for sensing devices

An electrode layer has a plurality of substantially parallel electrodes disposed along a first direction. At least one electrode has a length along the first direction and a width from a first edge to a second edge along a second direction transverse to the first direction. At least one electrode comprises across its width at least one edge section, at least one intermediate section, and at least one central section, wherein an intermediate section is disposed along the electrode width between an edge section and the central section. At least one electrode edge section and intermediate section includes a plurality of electrically isolated regions arranged in a pattern along the electrode length. An electrode conductive area of the edge section is less than an electrode conductive area of the intermediate section.

Touch sensor electrode with patterned electrically isolated regions

A conductive element in a touch sensitive device, such as an electrode in a mutual capacitive touch sensor, that includes conductors arranged in a location pattern that may be sensed and analyzed, and a position on the touch sensor determined therefrom.

Touch-sensitive device with electrodes having location pattern included therein

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.

Touch sensor having au-shaped electronically conducive micromesh

An electrode for a touch sensitive device includes micro-wire conductors arranged to define an electrically continuous area and to include interior regions that are electrically discontinuous. The electrically continuous area may be patterned according to a one pattern, and the interior pattern may be patterned according to another pattern.

Mesh patterns for touch sensor electrodes

An electrode for a touch sensitive device includes micro-wire conductors arranged to define an electrically continuous electrode trunk area, and including branching elements which extend outward from the electrode trunk area. The electrically continuous trunk area is patterned coincident an underlying reference mesh pattern, as are the branching elements.

A touch-sensitive device with stylus includes a touch panel, a stylus drive unit, a stylus sense unit, a touch panel drive unit, and a measurement unit. A touch by a stylus proximate to a touch panel electrode changes a capacitive coupling between the touch panel electrode and a stylus electrode. The amplitude of the response signal is responsive to the capacitive coupling between the touch panel electrode and the stylus electrode, and is measured to provide an indication of the position of the stylus electrode relative to the touch panel.

Touch sensitive device with stylus support

A touch screen display sensor is provided that includes a transparent touch-sensing element disposed upon the surface of a transparent substrate and a force-sensing element disposed within the transparent touch-sensing element. The force-sensing element includes two sets of bands of micromesh and can include a pressure-responsive material between the bands of micromesh. The bands of micromesh include traces of a metallic conductor. The sets of bands of micromesh are spaced apart and occupy substantially parallel planes.

Positional touch sensor with force measurement

A touch-sensitive device with stylus includes a touch panel, a touch panel drive unit, a stylus sense unit, and a measurement unit. A touch by a stylus proximate to a touch panel electrode changes a capacitive coupling between the touch panel electrode and a stylus electrode. The amplitude of the response signal is responsive to the capacitive coupling between the touch panel electrode and the stylus electrode, and is measured to provide an indication of the position of the stylus electrode relative to the touch panel.
