We designed, fabricated and tested an in-line portable moisture sensor for industrial applications, which comprises a sensor array that can detect the moisture content in plastic granulates at real time as well as all the necessary readout electronics for signal processing and communication. Measurement results performed with plastic pellets showed that the in-line portable moisture sensor can detect the moisture content with a precision of 100 ppm thus providing a very important control input, which is used to reduce the amount of energy consumed by industrial drying systems and also to enable added production time by avoiding the additional drying time caused by utilizing the fixed drying time recommended in the datasheet of the plastic granulate.

The design, fabrication and testing of a low-cost portable medical device for the detection and quantification of exosomes is presented in this paper. The portable medical device comprises a sensor array that can detect the presence of exosomes and quantify its concentration, a micro fluidic device that handles the human serum containing the exosomes, and all the necessary readout and control electronics. Measurement results performed with exosomes showed that the portable medical device can detect exosomes with a concentration of $2.5\mathrm{x}10^{8}/\mu \mathrm{L}$ thus paving the way to a wide range of diagnostic applications.

This paper presents an IoT sensing system for agricultural applications, which can monitor at real time the moisture content of grains stored in silo bags located in remote locations thus allowing to avoid costly grain losses and to optimize the logistics of post-harvesting operations. The system comprises a customized gateway that collects the sensor data and sends it to a satellite network as well as multiple sensing units, which can measure both the grain moisture content with a resolution of 0.1% and the air temperature and air humidity inside the silo bags that are used together to assess the quality and condition of grains. The details about the modeling, design and fabrication of the proposed system together with the experimental results obtained during field tests are reported.

The design, fabrication and testing of a wearable medical device for remote monitoring the health of elderly people at home are presented in this paper. The proposed wearable medical device comprises a wide range of sensors, innovative sensor fusion algorithms and flexible electrodes that make possible to continuously run analyses such as hydration assessment, stress assessment, body temperature assessment, fall detection and heart monitoring. In-vivo measurement results showed the excellent performance of this wearable medical device in real-life scenarios.

This paper presents a smart sensor system capable of continuously and unsupervisedly monitoring the quality and condition of grains stored in silo bags located in remote locations. The system mainly comprises multiple sensing units, which can measure relevant physical and chemical parameters used to assess the grain moisture, the biological activity inside the silo bag and to detect a potential theft or vandalism. A prototype of the system was fabricated and experimental results obtained during field tests are reported.
