Title of the Presentation RF sensors for spectroscopic analysis of small liquid volumes
Abstract The use of RF-sensors is of interest for the study of biological materials as it gives an access to the internal properties of tissues or cells. These sensors are however sensitive to environmental conditions as temperature, affecting their reliability. The differential approach relying on the use of a known reference sample permits to compensate this effect; its implementation will be explained and the points of attention due to the possible overlap of the sensor resonances will be discussed. For different applications as medical diagnosis support or medicamental testing, the tested samples or of small volumes. As the sensing of small sample volumes implies reduced sensor sensitivity, resonating sensors can be preferred to broadband ones due to their higher sensitivity at the expense of the amount of frequency information. To mitigate this effect, the resonating sensor can be modified to make its resonance frequency electrically tunable. We will present the approach adopted to obtain a frequency tunable resonating sensor, along with the different parts of the system and the obtained performances.
