Abstract
Disclosed herein are electronic devices having a deformable surfaces through which a user can provide inputs to the device by applying a force such as a pinch or a squeeze. A particular embodiment is an earpiece with the deformable surface part of an elongate section extending from an earbud. The deformable surface includes an incompressible hyperelastic material and a pressure sensor. The pressure sensor includes a pressure sensing element and a void defined between the pressure sensing element and the incompressible hyperelastic material. An applied force is transferred by the incompressible hyperelastic material to compress the void and change an internal pressure thereof. The changed pressure is detected by the pressure sensor, and can result in changed operation of the electronic device.
