Development of microwave gas sensors

Sensors and Actuators B: Chemical, 2011
Abstract This work presents a novel approach in gas detection by an original method of microwave transduction. The design of the sensor includes a coplanar grounded wave guide with a gas sensing material to study its sensitivity to ammonia in argon flux.

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.

New type of microwave position sensors

2015 12th International Conference on Telecommunication in Modern Satellite, Cable and Broadcasting Services (TELSIKS), 2015
In this paper a new type of microwave position sensor is introduced. It is an angular microstrip sensor based on a slot etched in the ground plane. It is a microstrip stub resonator with slow-wave effect induced by the slot. Covering the slot decreases slow-wave effect and increases resonant frequency.

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.

Microwave Sensor Applications in Industry

17th European Microwave Conference, 1987, 1987
Microwave measuring methods can be applied to determine the properties of materials and hence it is possible to develop microwave sensors for processing industry. The first applications were in moisture measurement but lately many new sensor applications have appeared.

Industrial Microwave Sensors—A Review

Subsurface Sensing Technologies and Applications, 2000
This paper reviews the field of microwave sensors. The field is broad and the applications numerous. This review will therefore only be able to present the broad outlines. Firstly the historical perspective and the physical background are briefly described, and the general advantages and disadvantages are listed.

Microwave Sources, Sensors, and Devices

1992
The generation of microwaves has been the main impediment to the development of microwave systems until the late 1930’s, when the first practical microwave sources were developed. Naturally, these were essentially vacuum tubes but the principles involved had to be different than those used for low frequency vacuum tubes. The limitations of interelement
