Piezoelectric buzzers find wide use as audible-signal generators because of their low power consumption and clear, penetrating sound. An external driver or a self-driven circuit that oscillates at the ...

Energy-harvesting, or “scavenging,” systems extract energy from the ambient environment. Unfortunately, these power generators supply much less energy than do standard batteries. However, thanks to ...

This file type includes high resolution graphics and schematics when applicable. Piezo ceramics are brittle, difficult to connect electrical leads to, and have no insulating protection to prevent ...

Scientists have developed a new algorithm and circuit technology allowing high-frequency piezoelectric resonators to be used for phase locked loops (PLL). It was confirmed that these operate with low ...
