Surface acoustic wave microsensors.
The Journal of the Acoustical Society of America, 1996Surface acoustic waves (SAWs) excited on the surface of piezoelectric crystals form the basis of a family of microsensors that is sensitive, portable, cheap, and small. These microsensors can be used in a wide variety of applications to sense low levels of gases, physical quantities such as mass, temperature, pressure, flow and humidity, biological ...

Nonlinear surface acoustic waves: Theory
Ultrasonics, 2008A theoretical description is given for the propagation of surface acoustic wave pulses in anisotropic elastic media subject to the influence of nonlinearity. On the basis of nonlinear elasticity theory, an evolution equation is presented for the surface slope or the longitudinal surface velocity associated with an acoustic pulse.

Surface Acoustic Wave Microfluidics
Annual Review of Fluid Mechanics, 2014Fluid manipulations at the microscale and beyond are powerfully enabled through the use of 10–1,000-MHz acoustic waves. A superior alternative in many cases to other microfluidic actuation techniques, such high-frequency acoustics is almost universally produced by surface acoustic wave devices that employ electromechanical transduction in wafer-scale ...

Surface acoustic wave filter, surface acoustic wave device and communication device
The Journal of the Acoustical Society of America, 2007A longitudinally coupled resonator type surface acoustic filter includes a rotated Y-cut X-propagating LiTaO 3 substrate. The gap length G in the IDT electrode of the surface acoustic wave resonator is about 0.3 times the wavelength λ of the surface acoustic wave or less.

Surface Acoustic Wave (SAW) Filters
2007Lumped components such as resistors, capacitors, and inductors make up most of the glue that allows microwave discrete transistors and integrated circuits to work. Lumped components provide impedance matching, attenuation, filtering, DC bypassing, and DC blocking. More advanced lumped components such as chokes, baluns, directional couplers, resonators,

A surface acoustic wave device that can operate in alternate-phase mode and single-phase mode, and thus generate surface acoustic waves at two different frequencies. The device is based on a piezoelectric film deposited on an elastic substrate, and includes an electrode layer patterned as two interdigital electrodes and electrical source (2).
