Latest Patents
Hsieh holds a patent for the "Structure of a three-electrode capacitive pressure sensor." This invention presents a unique structure and production method that integrates sensor capacitors and reference capacitors within the same pressure sensor cavity. The dual capacitor integration structure effectively cancels environmental interference of the same mode through a differentiated circuit. The design avoids the need for connections between upper and lower electrode plates by incorporating a third electrode plate. In a working pressure interval from 25 psi to 40 psi, the sensitivity of this three-electrode capacitive sensor is measured at 0.21 pF/psi, significantly higher than the 0.05 pF/psi sensitivity of conventional planar connection pressure sensors. The advantages of this innovative sensor include a simplified production procedure and enhanced sensitivity.
