The "harmonic scalpel," in contrast, uses ultrasonic vibrations that move a cutting blade 55,000 times per second.
Dr. Walker says her own research shows that a simple change in surgery -- using a tool powered by ultrasonic vibrations that cut tissue and stop bleeding simultaneously -- can get children to swallow normally again faster than a standard tonsillectomy.
In March, the university announced the review after concerns had been raised over the research of the professor, Rusi P. Taleyarkhan, who claimed to have induced fusion by blasting a container of liquid solvent with ultrasonic vibrations.
Fusion is the process the sun uses to produce heat and light, and scientists led by Rusi P. Taleyarkhan, a professor of nuclear engineering at Purdue, said they were able to achieve the same feat by blasting a container of liquid solvent with strong ultrasonic vibrations.
The "UltraHaptic" system uses an array of ultrasonic transducers – a grid of small piezoelectric speakers that produce waves of ultrasound, the same as those used to scan babies in the womb – which align to produce an invisible layer of ultrasonic vibrations in the air above a display.
"Our membrane screen can be controlled using ultrasonic vibrations.
uBeam's charging case converts the ultrasonic vibrations fired from the transmitters into energy.
Ultrasonic vibrations are typically generated by a piezoelectric actuator.
Ultrasonic vibrations break the nanowires close to their interface with the AAO template.
CD without any ultrasonic vibrations was performed by using a new orthopedic drill bit.
Piezoelectric devices are specially designed for osseous surgery and use low-frequency ultrasonic vibrations.
