  • Patent number: 11767218
    Abstract: According to an example aspect of the present invention, there is provided a MEMS pressure sensor, comprising: a sensor portion comprising a deformable membrane and a first volume, and a valve portion comprising a first output to a first side of the pressure sensor and a second output to a second side of the pressure sensor. The valve portion is operable to close the second output and open the first output to equalize pressure in the first volume with pressure at the first side of the pressure sensor for calibrating the sensor; and close the first output and open the second output to equalize pressure in the first volume with pressure at the second side of the pressure sensor for pressure measurement.

  • Publication number: 20220117533
    Abstract: In some embodiments, a system includes a patch assembly, a frame, and a conductive component. The patch assembly is configured to be coupled to a patient via an adhesive portion. The patch assembly includes an electronics subassembly. The frame has a first frame configuration in which the frame is coupled to the patch assembly via a plurality of connectors and a second frame configuration in which the plurality of connectors are broken and the frame is separated from the patch assembly. The conductive component forms a continuous loop when the frame is in the first frame configuration. A portion of the conductive component is broken when the frame is in the second frame configuration such that the conductive component is discontinuous between the first end and the second end. The portion of the conductive component is at least partially disposed on a connector from the plurality of connectors when the frame is in the first frame configuration.
