Abstract

The differential pressure sensors are used for various applications. In this work, a piezoelectric differential pressure sensor using an aluminum nitride (AlN) thin film cantilever is proposed to achieve high sensitivity and low power consumption. The dimensions of the cantilever are 1500 μm × 1000 μm × 2 μm. The proposed sensor needs no power consumption in the AlN sensing element in principle. The sensor design was validated by measuring the performance of the sensor, which showed sensitivity of 8.2 mV/Pa from -20 Pa to 20 Pa
