With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

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 ...

Researchers have developed a wireless energy source that generates electricity from simple mechanical motion, such as the waves in the ocean, the tap of a foot or the clap of a hand. Researchers from ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

Motion electricity generator: Using charge generated by body motion, BISS can power wearable and implantable devices such as smart glasses, wristbands or cardiac ...
