Passive Strain Sensor using SH-SAW Reflective Delay Line
Ferroelectrics, 2006 A shear horizontal-mode surface acoustic wave (SH-SAW) has the unique characteristic of complete reflection at a free edge normal to the direction of propagation, making it possible to construct a reflective delay line. A passive SAW strain sensor based on such a reflective delay line is presented.

PM2.5 detection by cyclone separator combined with SH-SAW sensor
2017 IEEE 12th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2017 In this research, a particulate matter PM2.5 monitoring device is designed and developed, including the shear horizontal surface acoustic wave (SH-SAW) sensor combined with a cyclone separator. Aerosols generated by incense smoke will be separated and sampled inside the designed cyclone separator first, and the sampled PM2.5 particles will be ...

The velocity and attenuation changes of shear horizontal surface acoustic wave (SH-SAW) biosensors with viscosity changes as a function of the operating frequencies are studied. It is confirmed that the velocity and attenuation changes of SH-SAW biosensors to the viscous changes are proportional to the square root of the frequency using the numerical ...

This paper describes a shear horizontal surface acoustic wave (SH-SAW) immunoassay biosensor on a quartz substrate. The SH-SAW biosensor is a 250MHz SH-SAW delay-line which has a gold surface covered with antibodies. It is important to discuss the detection mechanism of SH-SAW biosensors on quartz.

Enzyme-immobilized SH-SAW biosensor
Sensors and Actuators B: Chemical, 1994Abstract A shear horizontal mode surface acoustic wave (SH-SAW) device has many attractions for chemical-sensing applications in liquid media. The SH-SAW that propagates on 36° rotated Y-cute, X-propagating LiTaO3 is affected by a strong acoustoelectric interaction between the piezoelectric potential and electric properties of the adjacent liquid ...

SH-SAW Sensor for Superfluid 3He
Journal of Low Temperature Physics, 2005We have developed a new technique to study the transverse acoustic properties of superfluid 3He, employing a shear horizontal surface acoustic wave (SH-SAW) sensor. The transverse acoustic impedance can be obtained from the velocity and damping of SH-SAW which acoustically couples with liquid 3He all the interface. Since ultrasonic measurements provide

Liquid Identification Using SH-saw Sensors
Proceedings of the International Solid-State Sensors and Actuators Conference - TRANSDUCERS '95, 2005The objective of this paper is to present a new application of shear horizontal surface acoustic wave (SHSAW) devices on 36" rotated Y-cut X-propagating LiTaOs for a sensing system that can identify liquid samples. Theoretical sensor sensitivity for acoustoelectric interaction with a liquid loaded on the SAW propagation surface was derived and ...

This work has investigated some methods to solve the problems of non-steady operation and temperature interference which were easy to find in the shear horizontal surface acoustic wave (SH-SAW) sensing applications such as the gas sensor, liquid sensor and immunosensor. A programmable PLL circuit and independent LO input were applied to the multi-mixer
