Researchers have conducted a comprehensive study on a bio-inspired microphone that utilizes a tunable piezoelectric cantilever array. The study appears to be related to other research on piezoelectric microelectromechanical systems (MEMS) and their applications, including speakers, artificial basilar membranes, and acoustic transducers. The scope of the research encompasses various aspects, including the development of MEMS microphones and speakers, as well as their potential use in noise control and sound source localization.
