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.

Title of the Presentation
Sensitivity, selectivity and multi-parameter sensing with coupled planar microwave resonators

Abstract
This presentation proposes a comprehensive investigation into the design, analysis, and implementation of coupled planar microwave resonators optimized for advanced sensing applications. Planar microwave structures are widely utilized for non-invasive characterization; however, achieving simultaneously high sensitivity and selectivity remains a critical challenge. By exploiting the electromagnetic coupling mechanisms between resonators, we demonstrate a significant enhancement in the sensor's overall performance. This approach also enables the simultaneous extraction of several features  from an unknown material under test. Experimental and numerical results validate this approach, offering a high-precision, compact, and cost-effective outcomes opening the way for precise, accurate, real-time advanced industrial, chemical, and biomedical diagnostics.

From Large Experiments to Silicon Laboratories: How Mixed-Signal SoCs Are Reshaping Sensing and Connectivity

Abstract
Over the last few decades, sensing systems have evolved dramatically. Functions that once required bulky and complex instrumentation can now be integrated into a few square millimeters of silicon. This integration is leading to a new class of all-in-one detectors that combine sensing, signal processing, and communication capabilities on a single device. Drawing on examples from particle physics instrumentation and the development of compact sensor systems, this talk will explore how advances in mixed-signal System-on-Chip technologies are enabling an emerging generation of connected, distributed sensing platforms. The convergence of microelectronics, wireless communications, and edge intelligence is opening up new possibilities in environmental monitoring, smart cities, wearables, and health applications. Finally, the presentation will discuss how the concept of a "silicon laboratory" is already reshaping the way measurements are performed and interpreted, turning technological expectations of the last decade into practical reality.
