Abstract: An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

Abstract: Transparent conductors including a silver layer with high transparency and low sheet resistance are described. In some examples, the silver layer can be located between two transparent conductive oxide layers. The transparent conductor can further include additional transparent conductive oxide layers, optical layers, and/or additional conductive layers (e.g., layers including ITO or another fully or partially transparent conductive material), for example. In some examples, transparent conductors including a silver layer can be included in a touch screen device. For example, one or more shielding layers or one or more touch electrodes can include transparent conductors with a silver layer. In some examples, the silver layer can improve transparency, sheet resistance, and/or infrared reflection characteristics of the transparent conductor.
