A team of engineers at the University of California San Diego has developed a stretchable ultrasonic array capable of serial, non-invasive, three-dimensional imaging of tissues as deep as four ...

Haptic feedback has become a common feature of recent technology, but such systems usually rely on stimulation of parts of the user’s body via direct mechanical or acoustic vibration. A new technique ...

We’ve all seen acoustic levitation, it’s one of the scientific novelties of our age and a regular on the circuit of really impressive physical demonstrations of science to the public. The sight of ...

Ultrasonic transducers are incredible, with them you can detect distances, as well as levitate and peer through objects. They can emit and receive ultrasonic soundwaves (typically above 18khz) and ...

A team of research physicists at the University of Dundee in Scotland have created an ultrasound array that can effectively be used as a sonic screwdriver, right out of Doctor Who. The Dundee ...

The question of whether invasive or noninvasive methods provide the best possible outcomes for patients with ...

In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...
