In the wave of modern technology, high-power wireless charging technology is reshaping the paradigm of energy transmission.

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Inductors are more like a resistor in series with an ideal inductor, resistors can be inductors as well, and well, capacitors aren’t just simply a capacitance in a package. Little with electronics is ...

Harmonic distortion is not a problem unless it becomes a problem. Harmonics are a breakdown of a distorted waveform into its separate frequencies, which are integer multiples of the fundamental ...

The advantages provided by eGaN FETs in hard switching isolated and non-isolated applications have been addressed previously. Here, we demonstrate the ability of the eGaN FET to improve efficiency and ...

Living human cells have resonant frequencies – rates at which they will naturally oscillate if the conditions are right. This has been suspected for decades, but researchers have now measured what ...

Some cool-mist humidifiers work by flinging water at a vaporizer, but our favorite kind uses a piezoelectric transducer. These work by using high-frequency sound waves to pound the surface of the ...
