Abstract: A force input sensor includes a load cell to adapt a compressive force applied to the force input sensor into a strain experienced by a strain sensor in the load cell. In particular, the load cell includes two compression plates separated from one another by a gap so as to define a volume between them. A flexible substrate (a “diaphragm”)—includes a strain sensor and is disposed and supported within the volume. One of the two compression plates includes a feature (a “loading feature”) that extends toward a central region of the flexible substrate. As a result of this construction, when the compression plates receive a compressive force, the loading feature induces a bending moment in the flexible substrate, thereby straining the strain sensor.

Abstract: An electronic device has sensors. More particularly, the electronic device is a small form factor electronic device such as earbuds, styluses, or electronic pencils, earphones, and so on. In some implementations, one or more touch sensors and one or more force sensors are coupled to a flexible circuit. In various implementations, the touch sensor and the force sensor are part of a single module controlled by a single controller. In a number of implementations, the flexible circuit is laminated to one or more portions of an interior surface of the electronic device.
