A common enhancement to this circuit replaces R2 with an inductor as shown in Figure 2.. Figure 2 Substituting an inductor for R2 improves the piezo driver’s output and efficiency.. Often the ...

An unusual application of a piezoelectric transducer serves as an oscillator and drives a white LED (Figure 1). The piezoelectric diaphragm, or bender plate, comprises a piezoelectric ceramic plate, ...

The circuit is designed for atomizing transducers, which have a resonant frequency of 113 KHz — much higher than your average junk box piezo. Check out the demo and build video after the break.

NICT develops circuit technology that resolves issues with high-frequency piezoelectric resonators. by National Institute of Information and Communications Technology (NICT) ...
