Researchers have demonstrated a technique for detecting and controlling ultrahigh frequency sound waves at the nanometer scale. This represents an advance towards next generation ultrasonic imaging ...

Radio-frequency (RF) control of an ultrasonic phononic crystal was achieved by encapsulating it in a composite of high k-10% KF-doped BaTiO 3 dielectric nanoparticles with poly(N-isopropylacrylamide) ...

Commercial devices that produce ultrasound frequencies are not promising tools for repelling bed bugs, according to new research. Alternative means of controlling urban insect pests by using ...

What do bats, dolphins, shrews, and whales have in common? Echolocation! Echolocation is the ability to use sound to navigate. Many animals, and even some humans, are able to use sounds in order to ...

The future is wireless power, or so say a thousand press releases in my spam folder, and with very few exceptions every single system of wireless power delivery has fallen flat on its face. Except for ...
