Abstract
An acoustic transducer arrays was designed and developed for imaging application. There were two type of design and namely as single linear transducer array and dual linear transducer array. The transducer array has been break up into three different pitch element designs, 0.5 mm, 0.8 mm and 1.5 mm. The acoustic transducer array has been developed using polyvinylidene fluoride (PVDF) sheet and deposited on printed circuit board (PCB). The sensitivity of all transducers are evaluated and analysed. The setup measurement are based on reciprocity calibration method. The sensitivity of acoustic transducer array based on pitch element has shown in the result. The 1.5 mm pitch element gap has more sensitivity in 28 dB compare to 0.5 mm.
