Thin Rod Flexural Acoustic Wave Devices: A Sensor Candidate By C. K. Jen, J. C. H. Yu, Z. Wang, M. Viens, J. D. N. Cheeke and J. D. Dai Get PDF (2 MB). velocity, C, of the liquid surrounding the thin rod at a small value of fa, the energy which leaks to the liquid is minimal. Thus the thin rod flexural acoustic wave device is a good sensor candidate even when immersed in liquids. When a thin rod is immersed in a liquid, its velocity V «C) can be shown to be [12] V=(ma) (-E)1I4{ 1+-P o}-1I4. Thin Rod Flexural Acoustic Wave Devices: A Sensor Candidate. By C. K. Jen, J. C. H. Yu, Z. Wang, M. Viens, J. D. N. Cheeke and J. D. Dai. Abstract. In the past two decades there has been growing interest in the development of integrated acoustic sensors. Sensors based on bulk (BAW) [1,2] and surface (SAW) [3,4] were by: 2. An analysis of thin rod flexural acoustic wave gravimetric sensors is presented. The diameter of the thin rod is much less than a wavelength. The lowest order flexural acoustics mode, F 1 1, is of interest. For small added masses, the calculated mass sensitivity is −1/(2ρa), where ρ is the density and a is the radius of the thin rod.

  The mass sensitivities of the thin-rod acoustic wave sensor in both flexural and extensional acoustic modes are presented. These are based on experiments involving the electrodeposition of a test loading material onto a thin metal fiber (the thin rod) in a delay line configuration. Only small changes in acoustic loss occur when the device is immersed in an . An analysis of thin rod flexural acoustic wave gravimetric sensors is presented.

Thin Rod Flexural Acoustic Wave Devices: A Sensor Candidate. La Jolla, CA. In the past two decades there has been growing interest in the development of integrated acoustic sensors. Sensors based on bulk (BAW) [1,2] and surface (SAW) [3,4] were reported.   Acoustic wave devices, especially those based on surface acoustic wave (SAW), are one of the key building blocks for modern electronics, microsensors and acoustofluidics [,,, ]. These devices are generally manufactured on rigid substrates [ 17, 18 ], thus they are not suitable for applications that need flexible devices. Focusing on the physics of acoustic waves, as well as their propagation, technology, and applications, this book addresses viscoelasticity, as well as new concepts in acoustic microscopy. It updates coverage of ultrasonics in nature and developments in sonoluminescence, and it also compares new technologies, including use of atomic force acoustic microscopy and lasers.
