Reduction of surface acoustic wave resonator normal acceleration sensitivity using piezoelectric actuators" (2009).

Thermoacoustics describes energy conversion processes, activated by interaction temperature oscillation, accompanying the pressure oscillation in a sound wave, with solid boundaries. In ordinary experience this interaction of sound and heat cannot be observed, because of the very low temperature differences, but under suitable conditions, it can be emphasized and amplified to create remarkable ...

Mercury is the element commonly applied in industry. Because of poisoning properties the monitoring of the mercury vapour concentration in the environment is very important. Mercury forms amalgams in connection with gold that causes a change in the electrical resistance and mass of the gold specimens. This e ect was applied to measure mercury vapour concentration in the environment using surfac...

: We report that porous silicon acoustic Bragg reflectors and AlN-based transducers can be successfully combined and processed in a commercial solidly mounted resonator production line. The resulting device takes advantage of the unique acoustic properties of porous silicon in order to form a monolithically integrated bulk acoustic wave resonator.

A companion paper (Bell, 2001) formulated a model of the cochlea as a surface acoustic wave (SAW) resonator. This supporting paper seeks to give a working account of the sensing elements in the ear and how they operate together to create a SAW resonator. A key feature of any such device is that the interdigital transducers alternate in polarity, an arrangement ideal for launching and detecting ...

We report on recent experiments investigating the modification of the interband optical response of a piezoelectric semiconductor quantum well structure under the influence of intense short period surface acoustic waves. Experimentally, we study the photoluminescence (PL) of an undoped strained InGaAs/GaAs quantum well on which surface acoustic waves are propagated in the GHz regime. We observe...

Extraction of coupling of modes (COM) parameters from the manufacturing process of a surface acoustic wave device (SAW) is important in practice. In this study, we employed an inverse algorithm to recover the COM parameters from the measured admittance of a one-port SAW resonator. For completeness, the COM equations, the P-matrix representation and the related COM parameters have been summarize...

The applicability and performance of linear solvation energy relationships (LSERs) as models of responses from polymer-coated acoustic-wave vapor sensors are critically examined. Criteria for the use of these thermodynamic models with thickness-shear-mode resonator (TSMR) and surface-acoustic-wave (SAW) vapor sensors are clarified. Published partition coefficient values derived from gas-liquid ...
