An LC resonant pressure sensor with improved performance is presented in this paper. The sensor is designed with a buried structure, which protects the electrical components from contact with harsh environments and reduces the resonant-frequency drift of the sensor in high-temperature environments. The pressure-sensitive membrane of the sensor is optimized according to small-deflection-plate th...

Blood-gas data from a large interlaboratory survey were analyzed to determine whether pO2 and pCO2 results are affected by the atmospheric pressure at the measuring location. A small but statistically significant dependence was found, averaging about 2.3% per 100 mmHg (1.7% per 10 kPa) for pO2 and 1.0% per 100 mmHg (0.75% per 10 kPa) for pCO2.

OBJECTIVE To validate an intracochlear piezoelectric sensor for its ability to detect intracochlear pressure and function as a microphone for a fully implantable cochlear implant. METHODS A polyvinylidene fluoride (PVDF) piezoelectric pressure sensor was inserted into a human fresh cadaveric round window at varying depths. An external sound pressure stimulus was applied to the external audito...
