Abstract:This study provides a comprehensive characterization of a 4 × 4 PMUT array suited for in-air applications. Crosstalk can be viewed as a lack of isolation among the transducers, with possible reasons including the electrical, acoustic, and structural coupling among the transducers. This study focuses on acoustic coupling as the primary cause of crosstalk, since the influence of electrical and structural coupling on crosstalk is shown to be negligible by comparing experimental tests and numerical analysis conduc… Show more
