Mechanical vibrations refer to the rapid back-and-forth movement of an object or system. It is the shaking or oscillation of something, often caused by a force or an energy source. Full definition
Flexible plastics that turn mechanical vibrations into electrical energy could spur the development of self - powered sensors and devices. (sciencedaily.com)
This is not true, except perhaps in the plasma state, gases have a limited number of natural mechanical vibration frequencies or wavelengths due to their particular physical structure. (wattsupwiththat.com)
In their studies, Bahl's research group uses the extremely minute forces exerted by light to generate and control mechanical vibrations of microscale and nanoscale devices — a field called optomechanics. (sciencedaily.com)
