   en.wikipedia.org/wiki/Sonic_weapon

   Sonic weapon. A long-range acoustic device (LRAD) in use on the USS Blue Ridge. Sonic and ultrasonic weapons (USW) are weapons of various types that use sound to injure or incapacitate an opponent. Some sonic weapons make a focused beam of sound or of ultrasound; others produce an area field of sound. As of 2023 military and police forces make ...

3. Ultrasonic machining - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_machining

   An ultrasonic drill from 1955. Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. The tool travels vertically or orthogonal to the surface of the part at ...

4. Harmonic scalpel - Wikipedia

   en.wikipedia.org/wiki/Harmonic_scalpel

   A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation. This technique causes minimal energy transfer to surrounding tissue ...

5. iknife - Wikipedia

   en.wikipedia.org/wiki/Iknife

   iknife. An onkoknife, iKnife, or intelligent scalpel is a surgical knife that tests tissue as it contacts it during an operation and immediately gives information as to whether that tissue contains cancer cells. [1] During a surgery this information is given continuously to the surgeon, significantly accelerating biological tissue analysis and ...

6. Ultrasonic/sonic driller/corer - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic/sonic_driller/corer

   Ultrasonic/sonic driller/corer. The Ultrasonic/Sonic Driller/Corer (USDC) is a drilling device that uses vibrations in order to hammer its bit through materials, as opposed to traditional drilling methods. The drill uses a piezoelectric actuator as its source of power, and utilizes a variety of 'horns' to vibrate, or hammer, its bit through the ...
