    Abstract: An electronic device has a keyboard with an internal membrane. The membrane has a set of strain gauges configured to respond to a key press, such as when a collapsible dome collapses into contact with the membrane. The strain gauges are connected in a half Wheatstone bridge configuration and are positioned on the membrane in order to limit effects of temperature and subtle flexure of the membrane. The strain gauges are also configured to magnify detection of a resistance differential when a keycap is pressed with sufficient force.

    Abstract: Embodiments include a temperature sensing device that includes a temperature sensor stack that includes a flexible substrate and an array of temperature sensors coupled to the flexible substrate. Each temperature sensor in the array of temperature sensors can include a conductive material defining a continuous pattern extending from a first node to a second node, a first set of conductive traces coupled to the flexible substrate, and a second set of conductive traces coupled to the flexible substrate. The temperature sensing device can include a processing circuit configured to apply an electrical signal across the conductive material of each temperature sensor using the first set of conductive traces, detect an effect of the conductive material of each temperature sensor on the electrical signal using the second set of conductive traces, and determine a temperature for the temperature sensors in the array using the detected effects of the conductive material on the electrical signal.

    Abstract: One or more strain sensors can be included in an electronic device. Each strain sensor includes a strain sensitive element and one or more strain signal lines connected directly to the strain sensitive element. The strain sensor(s) are used to detect a force that is applied to the electronic device, to a component in the electronic device, and/or to an input region or surface of the electronic device. A strain sensitive element is formed or processed to have a first gauge factor and the strain signal line(s) is formed or processed to have a different second gauge factor. Additionally or alternatively, a strain sensitive element is formed or processed to have a first conductance and the strain signal line(s) is formed or processed to have a different second conductance.

    Abstract: A transparent structure may have layers with curved cross-sectional profiles. The transparent structure may have inner and outer layers with curved portions formed by bending the layers. A display may be applied to one or more of the inner and outer layers. To reduce the strain applied to the display while being bent into a desired curvature, a carrier film may be used during bending operations. The carrier film may be modified with a patch or openings distribute the strain evenly across the display. Additionally or alternatively, a convex mold may be used to further decrease the strain on the display while being formed into the desired curvature.
