Most modern surface acoustic wave sensors use an input interdigitated transducer ( IDT ) to convert an electrical signal into an acoustic wave.

In 1981, he joined Purdue University, where he is ( since 1999 ) the Thomas Duncan Distinguished Professor in the Surface Acoustic Wave Devices.
23.
In 2001 its space products division opened an approximate $ 7M Surface Acoustic Wave ( SAW ) development and manufacturing laboratory in its Cambridge facility.
24.
The accumulation of mass on the surface of an acoustic wave sensor will affect the surface acoustic wave as it travels across the delay line.
25.
Thus, this method is most efficient with the utilization of surface acoustic waves, and studies on investigation of this method toward lateral structures are being conducted.
26.
These motors are also known as inchworm motors Another mechanism employs the use of surface acoustic waves ( SAW ) to generate linear or rotational motion.
27.
A common example of an electroacoustic resonator is the surface acoustic wave ( SAW ) and, bulk acoustic wave ( BAW ) have been used for filters.
28.
When exposed to ultraviolet radiation, zinc oxide generates charge carriers which interact with the electric fields produced in the piezoelectric substrate by the traveling surface acoustic wave.
29.
In seismology surface acoustic waves travelling along the Earth's surface play an important role, since they can be the most destructive type of seismic wave produced by earthquakes.
30.
Moreover, with the gentle, bio-compatible nature of low-power surface acoustic waves, the acoustic tweezers is expected to be able to preserve the integrity of cells and other bioparticles.
