| 21. | To meet the resolution requirements of manipulating single cells, short-wavelength acoustic waves should be employed.
|
| 22. | Other types of delay line include acoustic ( usually magnetostrictive, and surface acoustic wave devices.
|
| 23. | We note that acoustic waves of 100 GHz to 1 THz have wavelengths in nanometre range.
|
| 24. | Like capacitive screens, acoustic wave screens are robust.
|
| 25. | Surface acoustic wave humidity sensors require a thermoelectric cooler in addition to a surface acoustic wave device.
|
| 26. | As an acoustic wave propagates through the tissue, part of it is absorbed and converted to heat.
|
| 27. | With megasonics, the acoustic wave is found only in a line of sight from the transducer surface.
|
| 28. | Surface acoustic wave humidity sensors require a thermoelectric cooler in addition to a surface acoustic wave device.
|
| 29. | Acoustic waves themselves are waves of mechanical motion : of air molecules or some other fluid medium.
|
| 30. | Surface acoustic wave devices can be used to measure changes in viscosity of a liquid placed upon it.
