Surface Acoustic Wave Based Magnetic Sensors
Since the radar system was invented in 1922, the development of devices communicating by means of reflected power has experienced a continuously growing interest. In 1948, Harry Stockman published a paper [1] in which he laid the basis for the idea of radio frequency identification (RFID), and the first patent had been filed in 1973 by Charles Walton. After decades of research and commercializa...
متن کاملSurface Acoustic Wave (SAW) Vibration Sensors
In the paper a feasibility study on the use of surface acoustic wave (SAW) vibration sensors for electronic warning systems is presented. The system is assembled from concatenated SAW vibration sensors based on a SAW delay line manufactured on a surface of a piezoelectric plate. Vibrations of the plate are transformed into electric signals that allow identification of the sensor and localizatio...
متن کاملSensing Materials for Surface Acoustic Wave Chemical Sensors
Online real‐time monitoring of gases requires a miniaturized, passive, and accurate gas sensor. Surface acoustic wave (SAW) devices possess these properties which make them suitable for gas‐sensing applications. They have shown remarkable results in sensing of different gases in terms of sensitivity, selectivity, response, and recovery times. One of the important prerequisites a designer should...
متن کاملSurface Acoustic Wave Sensors for Hydrogen and Deuterium Detection
A delay-line-type surface acoustic wave (SAW) sensor based on a zinc oxide (ZnO) sensitive layer was developed. Two types of sensitive layers were obtained: ZnO nanowires and ZnO thin films, both deposited using laser methods (VLS-PLD and PLD, respectively) onto quartz substrates. The responses of sensors with two different nanowire lengths (300 and 600 nm) were compared with those of sensors w...
متن کاملLangasite Membranes for Surface Acoustic Wave Pressure Sensors
On the basis of the electroelastic perturbation model, which includes electrical perturbation items, a doubly rotated cut area of langasite (LGS) defined by the Euler angles φ, from 137° to 160°, and ψ, from 18° to 25°, is proposed as a design for pressure sensors because it has good temperature stability (TCD < 10 ppm), high electromechanical coupling coefficients (k2 > 0.4%) and relatively hi...
