Abstract: This paper presents the fabrication, modeling, and characterization of a micromachined piezoelectric directional microphone. The microphone structure consists of a 20-μm-thick semirigid beam ...

This device provides both vision and audio feedback. The setup captures high-quality contact audio with a piezoelectric microphone. On the algorithm side, they address audio domain gaps with a ...

This tiny microphone, a sensor produced from a biocompatible piezoelectric material, measures miniscule movements on the underside of the ear drum. Piezoelectric materials generate an electric ...

The scientists’ past research had proved that the piezoelectric fabric could translate acoustic sounds into electricity—effectively turning the silk sheet into a microphone. To get the sheet ...

The work, presented in the journal Advanced Materials, builds on earlier research to create a silk-like fabric that can act as a microphone ... made out of piezoelectric fiber, is barely thicker ...

Perhaps it’s not the best microphone possible, with a somewhat heavy diaphragm and 3D printed body. But the hand-wound spring transmits the sound down to a piezo disk which serves as the ...

To wit, check out the following blurb also within Wikipedia’s definition of MEMS microphones: Since the 2010s, there has been increased interest and research into making piezoelectric MEMS microphones ...

Abstract: This paper describes a novel bimorph piezoelectric microphone built on a micromachined parylene diaphragm with two ZnO films of opposite c-axis orientations. Both the sensitivity and ...
