Piezoelectric buzzers find wide use in embedded systems for audible-signal generation. You can drive a piezoelectric element directly from a microcontroller’s I/O pins, but the maximum voltage rating ...

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 ...

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 ...

Piezoelectricity was discovered by two French scientists’ brothers, Jacques and Pierre Curie, in 1880. They found out about piezoelectricity after first realizing that pressure applied to quartz or ...
