Ultrasonic piezoelectric transducer design with concave surface

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

This paper introduces an ultrasonic piezoelectric transducer consisted of a concave shaped piezoelectric film and a support with an air cavity for vibration. The high flexibility and sensitivity of the transducer are guaranteed by utilization of Polyvinylidene fluoride (PVDF), and these are important in designing transducers of good acoustic performance. Ultrasound pressure results of the transducer are measured from frequency sweep inputs. From the results, we observe that the concave case generates several resonant peaks within a specific frequency range. Additionally, the sound pressure change of the transducers with different radii of curvature is investigated. The experimental results demonstrate that radius of curvature contributes to the sound pressure magnitude significantly.
