Abstract: The present invention relates to pressure sensor and more particularly self-calibrated miniaturized pressure sensor designed for monitoring applications in automotive, industrial, medical and consumer products. One of the advantages of the present invention is able to detect self-calibration of the pressure sensor at both the initial state of the device or during operation. Another advantage of the present invention is that the self-calibrated miniaturized pressure sensor of the present invention enables the user to know the exact condition of the deformed diaphragm structure to ensure that the measured results are representative of the actual applied external pressure instead of the internal mechanical failure of the diaphragm structure. The present invention further provides a considerable reduction of materials with even greater efficiency and economically during operation.
