Abstract
An electronic device having a pressure detection system is disclosed. The electronic device may include one or more elements designed to detect pressure exerted on the electronic device. In some embodiments, the electronic device includes a membrane and a detection mechanism, both of which bend in response to a pressure change at the membrane. The membrane may be electrically coupled with a circuit that detects the bending of the membrane and correlates the bending with a pressure change at the membrane. A can may be hermetically sealed with the membrane and surround the circuit to shield the circuit from liquid ingress. In some embodiments, a light transmitter and light receiver are used to detect the bending of the membrane. The light may reflect from the membrane at different angles, based upon a shape of the membrane, and contact the receiving element at different locations, corresponding to pressure change.
