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 ...

The humble piezo disc buzzer is much more than something that makes tinny beeps in retro electronic equipment, it can also be used as a sensor. Tapping a piezo buzzer gives an interesting waveform, ...

These small and strong materials offer a wide frequency range, suiting a variety of applications and specific design needs without sacrificing performance. Electronic engineers are no strangers to odd ...

Piezo elements have the useful property of being bidirectional; that is they can move when you apply electricity to them, but they can also generate electricity when you move them. [Carl] takes ...

ROHM has recently established a process for MEMS (micro electro mechanical system) using thin-film piezoelectric elements, and implemented a foundry business that is said to be the first based on the ...

Inside each tile are the piezoelectric elements—thin discs of lead zirconate titanate—along with several solar cells and a lithium battery for storing power generated during the day. Researchers at ...
