SAW-RFID enabled temperature sensor
Sensors and Actuators A: Physical, 2013Abstract Wireless sensors based on surface acoustic wave (SAW) technology has its own advantages over its counterparts. In this paper, a novel SAW radio frequency identification (RFID) enabled temperature sensor is proposed for industrial applications, in which short measurement range but high accuracy is usually required. The encoding scheme for the

This paper considers recent developments in surface acoustic wave sensors (SAWS) and illustrates the operating principle of both physical and chemical SAWS based on surface acoustic wave (SAW) propagation velocity variations. The SAWS that have appeared in the literature so far are qualitatively reviewed and compared with other existing sensors based ...

The design and performance of two types of SAW pressure sensors have been considered. SAW resonator oscillators with metal strip gratings designed for operation at 200 and 360 MHz have been used in both type devices to study the opportunity of the mechanical pressure measurement became of mechanical loading on Rayleigh surface wave propagation.

SAW temperature sensor on Quartz
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015For biomedical applications, narrow temperature range and high sensor accuracy requirements define the need for high temperature sensitivity. Wireless SAW sensors connected to antennas need a reference element to account for changes in electromagnetic coupling between the transmitter and receiver antennas.

Proceedings of IEEE 48th Annual Symposium on Frequency Control, 2002
This paper presents experimental data on the performance of some types of SAW sensors like, biosensor, gas sensor and pressure sensors. It is shown that such parameter, as sensitivity is determined by kind of piezocrystal cut and direction of SAW propagation as well as by the construction of sensor, method of treatment of signal, properties of covering

Wireless Interrogation of Implantable SAW Sensors
IEEE Transactions on Biomedical Engineering, 2020Implantable sensors provide long-term, accurate physiological measurements after a minimally invasive procedure, particularly when designed as transponders. Wireless interrogation of deeply implanted transponders with RF remains a challenge due to the high loss at the skin-air interface and large tissue RF absorption.

Precision SAW pressure sensors
1993 IEEE International Frequency Control Symposium, 2002The design and performance of two types of SAW (surface acoustic wave) pressure sensors are considered. SAW resonator oscillators with metal strip gratings designed for operation at 200 and 360 MHz have been used in both types of devices. The sensitivity and the nonlinearity of both sensors, a sensor with a sensitive element shaped as an integral ...

A new principle of designing a SAW gas sensor is described. This sensor, being essentially of sorption type, also offers properties of thermometric SAW sensors. The basic idea here is that heat fluxes propagate between the SAW substrate and the working surface of the temperature-regulating system with some delay.

2009 IEEE International Ultrasonics Symposium, 2009
This paper presents results for a 250MHZ orthogonal frequency coded (OFC) surface acoustic wave (SAW) cantilever device on YZ LiNbO 3 . A 1-D model is presented which predicts the variation in the wave velocity with applied strain. A FEM analysis is conducted which verifies the strain on the cantilever and supports the 1-D model predictions.
