SH-SAW liquid sensor for methanol concentration sensing

2010 IEEE International Ultrasonics Symposium, 2010
Operating Direct Methanol Fuel Cell (DMFC) at ideal condition, it is extremely important to measure fuel concentration and maintain it within a proper range. Fuel concentration measuring devices have been required. SH-SAW based methanol concentration sensor is one of promising candidate for DMFC.

Monitoring blood coagulation with QCM and SH- SAW sensors

IEEE Ultrasonics Symposium, 2005., 2006
Investigations concerning a coagulation sensor based on shear horizontal surface acoustic waves (SH-SAW) are described. As a first step, experimental work was focused on a simpler system: a quartz crystal micro balance (QCM) also called thickness shear mode resonator (TSM).

Liquid sensor probe using reflecting SH-SAW delay line

Sensors and Actuators B: Chemical, 2003
Abstract A new liquid sensor probe has been designed by using SH-SAW device. Shear horizontal mode surface acoustic wave (SH-SAW) has a unique characteristic of complete reflection at the free edges of the substrate. The SH-SAW are excited on a 36° YX LiTaO3 and the right angle edge of the substrate has been used to reflect the SAW.

Influence of particles in liquid on SH-SAW sensors

Proceedings of IEEE Sensors, 2004., 2006
Measurements of particles in liquid, such as suspension and slurry, are required in the fields of industries and environmental contamination. A shear-horizontal surface acoustic wave (SH-SAW) can work as a liquid-phase sensor. In this paper, the SH-SAW sensor is applied for detecting particles in liquid.

SH-SAW-based sensor for heavy metal ion detection

2015 Joint Conference of the IEEE International Frequency Control Symposium & the European Frequency and Time Forum, 2015
In this study, a shear horizontal mode surface acoustic wave (SH-SAW) sensor, was designed and fabricated for the detection of heavy metals. The SH-SAW sensor was photolithographically fabricated by patterning gold (Au) interdigitated electrodes (IDE) and reflectors on the surface of a 64° YX-LiNbO 3 based piezoelectric substrate.

SH-SAW devices as effective identification system for liquids

Proceedings of IEEE Ultrasonics Symposium ULTSYM-94, 1994
This paper describes a liquid-identification system using shear horizontal surface acoustic wave (SH-SAW) sensors. The SH-SAW sensors are fabricated on 36d-rotated Y-cut X-propagating LiTaO3. Since the piezoelectric crystal has a high electromechanical coupling coefficient, the SH-SAW sensor can detect electrical properties of the adjacent liquid with ...
