Abstract: An electronic device is disclosed. In some examples, the device includes one or more force sensors at its perimeter. The force sensors can be included in a gasket further comprising a rubber-like gasket cover and a compressible dielectric such as air or silicone, for example. A plurality of conductive plates can be embedded in the gasket cover with routing traces coupled thereto to sense a capacitance between the conductive plates. The gasket, including the one or more capacitive sensors, can be disposed between a cover glass and a lower housing of the electronic device. The capacitance of the one or more sensors can change in response to an applied force at the cover glass of the device. The change in capacitance can be sensed via the routing traces to measure the magnitude and, in some examples, location of the applied force.
