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 ...

In a recently published study in the journal EPSL neuroelectronics, researchers from The Pennsylvania State University and Washington University in St. Louis have introduced a modular 16-channel ...

The increasing miniaturization and sophistication of electronic products, ranging from consumer media devices to medical diagnostic tools to defense-related sonar applications, presents a bounty of ...

The average Hackaday reader is likely at least familiar with acoustic levitation — a technique by which carefully arranged ultrasonic transducers can be used to suspend an object in the air ...

Acoustic tweezers can control target movement through the interaction of momentum between an acoustic wave and an object. Due to their high tissue penetrability and strong acoustic radiation force, ...

Thanks to Freescale Semiconductor Medical Applications guide, I give you this crash course in how ultrasound works. This non-invasive technique uses sound waves to create images of what’s inside of ...
