Surface acoustic wave (SAW) devices and resonators harness acoustic waves propagating along the surfaces of piezoelectric materials to perform signal filtering, sensing and frequency control. These ...

Researchers at the University of Rochester, including optics graduate students Arjun Iyer (foreground) and Wendao Xu, designed acoustic cavities, or tiny echo chambers, to strongly couple surface ...

In both developed and developing countries, advanced point-of-care diagnostic systems are needed for testing patients outside centralized hospital laboratories and other such facilities. Diseases such ...

Electronics traditionally rely on harnessing the electron's charge, but researchers are now exploring the possibility of harnessing its other intrinsic properties. In a Nature Communications study, ...

A team of engineers has made major strides in generating the tiniest earthquakes imaginable. The team’s device, known as a surface acoustic wave phonon laser, could one day help scientists make more ...

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can ...

In 1885, an English scientist, Lord Rayleigh, had hypothetically shown 3 that waves could be propagated over the plane boundary between a vacuum (or an adequately rarefied medium, air for example), ...

(Nanowerk News) The continuing progress in miniaturization of silicon microelectronic and photonic devices is causing cooling of the device structures to become increasingly challenging. Conventional ...

Modern cellular and other wireless communication devices require extensive filter banks to provide isolation to the multitude of operating frequency bands not present in modern wireless devices.

Since the discovery of electricity, countless advancements in technology have relied on harnessing the electron’s charge, which is the fundamental principle behind most of traditional electronics. Now ...

Scientists identify two sound-driven mechanisms for generating orbital currents, merging acoustics with cutting-edge electron physics. (Nanowerk News) Electronics traditionally rely on harnessing the ...
