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.

Abstract: Systems and methods related to piezoelectric based force sensing in touch devices are presented. One embodiment, for example, may take the form of an apparatus including a touch device having a deformable device stack and a piezoelectric element positioned relative to the deformable device stack such that the piezoelectric element deforms with the deformable stack. Deformation of the piezoelectric element generates a signal having a magnitude discernable as representative of an amount of force applied to the touch 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: An input/output device for a computing device including one or more touch sensors and one or more force sensors. The touch sensors sense data including one or more locations at which a contact or near-contact occurs. The force sensor sense data including a measure of an amount of force presented at the one or more locations at which a contact occurs. The touch sensors and the force sensors responsive to signals occurring in response to whether the signals are in response to contact or in response to an amount of force. The input/output device also includes one or more circuits coupled to the touch sensors and to the force sensors, and capable of combining information from both sensors.

Abstract: An electronic device having one or more sensors is provided. The sensors may include any suitable type of sensor that emits or receives radiation (e.g., light waves) from the environment. The electronic device may include openings through which radiation may reach the sensors while keeping the sensors hidden from view. In some embodiments, the sensors may be placed underneath an opening used for an audio receiver such that radiation is piped to the sensors using a light path or a chamfered surface along the opening. In some embodiments, the sensors may be embedded in a screen such that the radiation emitted by the sensors exits the screen instead of being reflected on the screen. In some embodiments, the sensors may be placed along the periphery of the display, such that access to the sensors is provided via discontinuities in a gasket used to couple the display to the electronic device.
