[Jason] has continued to plug along with his sonar build and recently showed up a monostatic active sonar using a piezo element and microphone. Regular readers will remember [Jason’s ...

See all 100 here. Vesper’s recent launch of the VM101, a piezoelectric MEMS (microelectromechanical systems) microphone has achieved 68 dB typical signal-to-noise ratio (SNR) — the highest ...

For example, when you use some type of voice-recognition software, or even Siri on your smartphone, the microphone that you’re speaking into is probably using piezoelectricity. That piezo ...

In a conventional piezoelectric microphone, the electric field is generated by metal electrodes. But in a fiber microphone, the drawing process would cause metal electrodes to lose their shape.

The asymmetry of the molecules is what makes the plastic "piezoelectric," meaning that it changes shape when an electric field is applied to it.In a conventional piezoelectric microphone, the ...

barely usable piezo crystals instead of larger ones like [Collin] was able to produce. Undeterred, he decided to see if the stuff was any good, and rigged up a makeshift contact microphone using ...

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 ...

a biocompatible piezoelectric material. These PVDF layers are positioned on either side of a flexible printed circuit board (PCB), creating a microphone approximately the size of a grain of rice ...
