摘要： A multi-layer conductive coating is substantially transparent to visible light, contains at least one conductive layer comprising silver that is sandwiched between at least a pair of dielectric layers, and may be used as an electrode and/or conductive trace in a capacitive touch panel. The multi-layer conductive coating may contain a dielectric layer of or including zirconium oxide (e.g., ZrO2) and/or silicon nitride, and may be used in applications such as capacitive touch panels for controlling showers, appliances, vending machines, electronics, electronic devices, and/or the like. The coating may have increased resistivity, and thus reduced conductivity, compared to pure silver layers of certain coatings, in order to allow the silver-based coating to be more suitable for use as touch panel electrode(s).

摘要： An apparatus for combined capacitance and pressure sensing is described. The apparatus includes a multiplexer (75) having a plurality of inputs (76) and an output (F), a touch panel (29), and a front end module (3). The touch panel includes a layer structure (5; FIG. 15) comprising one or more layers, each extending perpendicularly to a thickness direction, the one or more layers including a layer of piezoelectric material (10; FIG. 15), the layer structure having first (6) and second (7; FIG. 15) opposite faces, and the layer(s) arranged between the first and second faces such that the thickness direction of each layer is perpendicular to the first and second faces. The touch panel also includes a plurality of first electrodes (8) disposed on the first face, each first electrode connected to a respective input of the multiplexer. The touch panel also includes at least one second electrode (9) disposed on the second face. The front end module is configured to receive an input signal (11) from the multiplexer output. The front end module includes a first stage (12) configured to provide an amplified signal based on the input signal, and a second stage comprising first (13) and second (14) frequency-dependent filters configured to receive the amplified signal and to provide respective first (16) and second (17) filtered signals. The first filtered signal has a first frequency bandwidth, and the second filtered signal has a second frequency bandwidth which has a relatively higher start-frequency than the first frequency bandwidth.

摘要： A haptic-enabled display device is presented. The haptic-enabled device has a display layer, a first electrode layer, an actuation layer, and an electrode patch. The first electrode layer is disposed on the display layer. The actuation layer is formed of a single piece of actuatable material. A first side of the actuation layer is disposed on the first electrode layer. The single piece of actuatable material of the actuation layer and the conductive material of the first electrode layer may have substantially the same area. The electrode patch may form a second electrode layer, and may be disposed on a second and opposite side of the actuation layer. The electrode patch is electrically connected to a region of the actuatable material, and has an area that is smaller than that of the single piece of actuatable material and smaller than that of the conductive material of the first electrode layer.
