Abstract: A capacitive gap force sensor includes a first electrode, a second electrode spaced apart from the first electrode, a first layer of dielectric material positioned between the first electrode and the second electrode, and a second layer of conductive material positioned between the first layer and the second electrode. The first layer has a first compression resistance less than a second compression resistance of the second layer. An effective capacitive sensing gap is defined between the first electrode and the second layer. The first layer is configured to compress or deform and alter the effective capacitive sensing gap when a force is received at the first electrode or the second electrode.

Abstract: An electronic device that is operable to provide electrical haptic output includes a touch surface and multiple haptic cells disposed on the touch surface. The multiple haptic cells include capacitors that are operable to store charges independently of each other and independently provide haptic output when touched by a body by discharging the stored charge to create a current. In this way, a wide variety of dynamically configurable haptic outputs can be provided without moving parts and without consuming the space and/or power used for haptic actuators that vibrate and/or otherwise move a mass.

Abstract: An earphone includes a speaker housing; a speaker positioned in the speaker housing; a stem extending from the speaker housing, the stem defining an input surface; a conductive object disposed within the stem; a flexible circuit positioned between the stem and the conductive object; a member positioned between the flexible circuit and the conductive object operable to allow the flexible circuit to move with respect to the stem; a force sensor electrode disposed within the flexible circuit; and a controller operable to determine an input to the earphone using a change in capacitance detected using the force sensor electrode, the change in capacitance corresponding to a non-binary amount of a force applied to the input surface. In some examples, the earphone further includes a touch sensor electrode disposed within the flexible circuit.

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.

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.
