Abstract: A device configured to sense a touch on a surface of the device. The device includes a cover and a force-sensing structure disposed below the cover. The force-sensing structure may be positioned below a display and used in combination with other force-sensing elements to estimate the force of a touch on the cover of a device.

Abstract: Systems for detecting an amount and/or location of a force applied to a device using a piezoelectric film are provided. One example system can include a transparent piezoelectric film for generating an electric charge in response to a deformation of the film. Electrodes positioned on opposite surfaces of the piezoelectric film can be used to detect the generated electric charge and determine an amount and/or location of force applied to the film based on the generated electric charge. In another embodiment, the system can include a capacitive touch sensor for determining a location of a touch event on the device.

Abstract: An optically transparent force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.

Abstract: A device configured to determine the location and magnitude of a touch on a surface of the device. The device includes a transparent touch sensor that is configured to detect a location of a touch on the transparent touch sensor. The device also includes a force-sensing structure disposed at the periphery of the transparent touch sensor. The force sensor includes an upper capacitive plate and a compressible element disposed on one side of the upper capacitive plate. The force sensor also includes a lower capacitive plate disposed on a side of the compressible element that is opposite the upper capacitive plate.
