    Abstract: In an example, an impact detector may include a sensor mounting bracket, a piezo film sensor assembly, and an interface circuit. The sensor mounting bracket may be attached to an impact sensing object. The piezo film sensor assembly may be coupled to the sensor mounting bracket. The interface circuit may be configured to obtain one or more generated signals from the piezo film sensor assembly. The interface circuit may be configured to reduce a first amplitude associated with a noise signal and may be configured to amplify a second amplitude associated with an impact signal. The impact signal may occur in response to a force being applied to the impact sensing object.

    Abstract: A handheld device includes an electronic display having an active area for presenting visual content and a bezel disposed around the electronic display. The bezel may have an opening allowing a person to view the active area. The handheld device also includes a force sensing system having a force sensing element that is disposed below an external surface of the bezel. The force sensing system may be configured to a sense a force on the bezel and to generate a sensor signal indicative of the force. The handheld device may further include a processor operable to receive the sensor signal and to execute a function based on the sensor signal.

    Abstract: Certain implementations of the disclosed technology may include systems, methods, and apparatus for common mode signal cancellation in force change detectors. An example embodiment of the disclosed technology includes a press sensor element configured to reduce or eliminate thermally induced signals. The sensor element includes a piezoelectric layer that includes a first surface in communication with a first layer. The first layer includes a first conductive region. The piezoelectric layer includes a second surface in communication with a second layer. The second layer includes a second conductive region, a third conductive region, and a non-conductive void region separating the second conductive region and the third conductive region. The second and third conductive regions are configured to substantially reduce a thermally-induced voltage change between two or more of the first, second and third conductive regions responsive to a corresponding temperature change of at least a portion of the piezoelectric layer.
