Description
Summary:碩士 === 國立成功大學 === 機械工程學系 === 104 === This study aims to present a design and fabrication process of micro-scale pressure sensor array, convert an applied contact force into an electrical signal by using the piezoelectric effect. Polyvinylidene Fluoride (PVDF) has been used direct measurement of the mechanical stress and large bandwidth electromechanical transduction. Seven sensing units each of active area of 1x1 mm^2 are constructed and accompanied with one-to-one well-designed charge amplifier. The sensor array is calibrated by using a gas shock tube, which can provide a pressure change with a very fast rise time. Finally, the calibrated sensor array was used to measure the shock wave in a micro-scale pulsed detonation tube.
