    Abstract: Disclosed herein are electronic devices having a deformable surfaces through which a user can provide inputs to the device by applying a force such as a pinch or a squeeze. A particular embodiment is an earpiece with the deformable surface part of an elongate section extending from an earbud. The deformable surface includes an incompressible hyperelastic material and a pressure sensor. The pressure sensor includes a pressure sensing element and a void defined between the pressure sensing element and the incompressible hyperelastic material. An applied force is transferred by the incompressible hyperelastic material to compress the void and change an internal pressure thereof. The changed pressure is detected by the pressure sensor, and can result in changed operation of the electronic device.

    Abstract: A transparent force sensor for detecting an applied force on a surface of a device. The transparent force sensor includes a transparent force-sensitive film having an array of strain-relief features oriented along a first direction. The transparent force-sensitive film is formed from a transparent piezoelectric material that exhibits a substantially reduced net charge when strained along a primary direction. The force sensor also includes a display element disposed on one side of the transparent force-sensitive film.

    Abstract: A force-responsive sensor incorporating a force-sensitive element is in communication with a power controller. The power controller changes one or more performance characteristics associated with the force-responsive sensor. A performance characteristic can include a bias voltage or current, a duty cycle, a sampling rate, and so on. The performance characteristic(s) can be changed in response to a touch event or based on an operational setting of the force-responsive sensor (or an electronic device incorporating the force-responsive sensor). Regulation of the performance characteristic(s) reduces power consumption of the force-responsive sensor.

    Abstract: A strain-sensitive structure includes two resistive structures connected in series and formed on one surface of a substrate. One resistive structure is formed with a first trace arranged in first trace pattern. The other resistive structure is formed with a second trace arranged in a second trace pattern. The first resistive structure is configured to experience strain in response to an applied stress on the substrate. The second resistive structure is configured to experience less strain in response to the applied stress on the substrate compared to the first resistive structure. Together the strain-sensitive structure and the substrate form a force sensing layer that can be included in an electronic device.

    Abstract: A force sensing device can be included in a display. Noise produced by various sources can be injected into the force signals produced by the force sensing device. Example noise sources include, but are not limited to, the display, Johnson or Thermal noise from the force sensing device, system noise, and magnetically-coupled or background noise produced by ambient light sources. A sampling scheme that includes one or more noise cancelling techniques can be employed to reduce the amount of noise in the force signals.
