“…Microwave reflectometry (MR) is a powerful tool for several monitoring and diagnostic applications [23][24][25][26]. The basic concept is to propagate an EM test signal and to analyze the reflected one [27][28][29][30][31] which contains useful information on the chemical and physical composition of the tissue.…”

Wearable technology in healthcare refers to medical devices for real-time monitoring of a wide variety of biomedical parameters of the human body. The Health 4.0 scenario has led to the rapid development of these systems in all fields of medicine. However, a wearable non-invasive device for skin health monitoring for skin hydration control or cancer prevention is still an open challenge. In this regard, this paper addresses the design and the implementation of a low-cost portable system for skin diagnostics purposes which is based-on microwave reflectometry technique. For this purpose, a specific sensing element (SE), connected to a miniaturized vector network analyzer (m-VNA) has been designed and assessed for the optimal detection of the variation of the dielectric properties of the skin. The proposed system has been validated, first, through full wave simulations, then, directly on human skin, demonstrating a good potential for achieving a fully wearable system for skin monitoring and diagnostics.

“…MR technique is a powerful method for a wide range of monitoring and diagnostic applications [21][22][23][24][25][26][27][28][29]. The principle behind this technique relies on measuring the reflection scattering parameter, S11(f) [30], of the sensing element (SE) when this is placed in contact with the material under test, and in relating it to the water content.…”

The environmental conditions and the humidity level are crucial factors in caring for artworks. The aim of this work is to propose a method for on-site non-invasive moisture monitoring of wooden artworks or structures. In this regard, a truncated open-ended coaxial probe was designed, implemented, and tested to sense (in combination with a miniaturized Vector Network Analyzer) the variations of water content in woods and stones. More in detail, for the experimental tests, two types of wood (seasoned fir and not seasoned fir) and a limestone, used in Italian Artworks and structures, were analyzed at different moisture levels.

“…Over the past two decades, the measurement of dielectric properties has profoundly impacted various scientific fields, including industry, building, heritage materials, and soil pollution assessment [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. In recent years, microwave-based sensors have emerged as valuable tools in the biological and biomedical domains, providing non-invasive methods for the early-stage prognosis of diseases, including malignancies [ 8 , 9 , 10 ]. The measurement of the dielectric properties of biological tissues has proven to be highly beneficial in biomedical and healthcare applications due to its high sensitivity, versatility, and non-invasiveness [ 11 , 12 , 13 , 14 ].…”

This paper presents a measurement procedure for analyzing the dielectric properties of cells using descriptive statistics. The study focuses on four cancer cell lines (MDA-MB-231 and MCF-7 breast cancer, SaOS-2, and 143B osteosarcoma) and DMEM culture medium, utilizing the Lorentzian fit model of the return-loss function. The measurements are performed using a circular patch resonator with a 40 mm diameter, powered by a miniVNA operating in the frequency range of 1 MHz to 3 GHz. Eight specimens are prepared for each group to ensure reliability, and the return loss is recorded ten times for each specimen. Various statistical parameters are calculated and evaluated, including the average value, standard deviation, coefficient of variation, and relative error between the average and the first values. The results demonstrate that one single acquisition highly represents the entire set of ten data points, especially for the resonant frequency, with an accuracy error lower than 0.05%. These findings have significant implications for the methodological approach to detecting cells’ dielectric properties, as they substantially reduce time and preserve the specimens without compromising the accuracy of the experimental results.
