  • Wearable electronic device with fluid-based pressure sensing
    Patent number: 11561144
    Abstract: An electronic device, such as a smart watch, incorporating a fluid-based pressure-sensing device is disclosed. The fluid-based pressure-sensing device includes an enclosure, a pressure sensor, a diaphragm and a sensing medium. The enclosure includes an opening and the pressure sensor is disposed inside the enclosure. The diaphragm hermetically seals the opening, and the sensing medium transfers a pressure exerted on the diaphragm to the pressure sensor. The sensing medium can be liquid oil filling a space of the enclosure, and the diaphragm is a polymer material. The pressure-sensing device may sense an environmental pressure, which may be used by the electronic device to modify its operations, change information that is displayed, and so on.
