Microwave Saw Humidity Sensor

2006 International Conference on Microwaves, Radar & Wireless Communications, 2006
In this paper the microwave humidity sensor has been presented. In the device the surface acoustic waves (SAW) resonator with nafion coating was used. The sensor exhibits good sensitivity and linearity as well as the resistance to active chemical compounds.

Microwave Acoustic Sensors

2019 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF), 2019
This paper will be a general overview on the sensing applications of micro-electro-acoustic devices, staring from the historical applications of the quartz resonator (Quartz Micro Balance) up to the large expansion produced by the exploitation of the specific performances related to use of Surface Acoustic Wave (SAW) structures and, more recently, the ...

Experiments with microwave sensors

International Journal of Remote Sensing, 1992
After an introductory first section, based on the previous history of microwave remote sensing in Europe, a review of achievements is presented in two parts. In the first the material is based on sensor development in the different European countries, whereas in the second non-European sensors are also included.

Microfluidics-based microwave sensor

Sensors and Actuators A: Physical, 2020
Abstract Microwave sensors offer attractive solutions to highly sensitive, rapid, and non-invasive measurements. Microfluidic technology has exquisite advantages of small size (manipulation of nanoliter sample volumes), low cost, and fast detection time.

Metamaterial Inspired Microwave Sensors

IEEE Microwave Magazine, 2012
Cheap and ubiquitous sensor systems will shape the coming decades. There is an emerging class of small high-performance electronic devices such as mobile phones, electronic toys, home appliances, monitoring and control systems in industrial facilities, and medical diagnosis systems, which are or will be equipped with pill box sized microprocessors or ...

Microwave ferrite acceleration sensors

IEEE Transactions on Electron Devices, 1969
This paper presents a new and potentially simple method of producing a frequency shift proportional to sensed acceleration in a passive microwave device. Magnetostriction effects in microwave ferrite rods are employed to convert an applied stress (acceleration) to a shift in resonant frequency.

BAW microwave temperature sensor

Proceedings of IEEE Sensors, 2004., 2006
The paper studies the possibility of using microwave high overtone bulk acoustic wave resonators (HBAR) in temperature sensors in liquids. The shear 430 MHz BAW are excited in the resonator structure providing high temperature sensitivity and relatively low harmful mechanical sensitivity of sensor on ambient liquid media.

BAW microwave temperature sensor

18th European Frequency and Time Forum (EFTF 2004), 2004
This work is aimed at the study of a potential possibilities of microwave Bulk Acoustic Wave resonators for temperature measurements. The resonators under study had nonstandard high overtone BAW resonator configuration: a thin piezoelectric film ZnO with electrodes was deposited onto the surface of the substrate made of the (100) oriented YAG plate ...

Intercalibration Between Special Sensor Microwave Imager/Sounder and Special Sensor Microwave Imager

IEEE Transactions on Geoscience and Remote Sensing, 2008
The F16 satellite was successfully launched on October 18, 2003, carrying the first special sensor microwave imager/sounder (SSMIS) onboard. In this paper, the SSMIS imaging channels 12-18 are intercalibated against the F15 special sensor microwave/imager (SSM/I) instrument using simultaneous conical overpassing (SCO) observations from both satellites.
