Sensors play an essential role in numerous sectors of interest for the Internet of Things, from home automation to automotive, biomedical engineering to the food and packaging sector or even precision agriculture. The physics of matter contributes to the understanding of microscopic phenomena underlying the detection mechanism and reveals the interactions that occur at the interface between the sensitive material and the surrounding environment. The long experience of the group in the physics of materials and the consolidated experience in controlling their morphology and their dimensions, has allowed to develop innovative nanostructures applied in simple demonstration devices with high performance.
Electrochemical Sensors
Faculty: E. BrunoM.G. GrimaldiS. Mirabella, F. Priolo, F. Ruffino, A. Scandurra
Electrochemical sensing techniques are very versatile and at the same time low energy consumption. These techniques, combined with the use of nanostructured electrodes of transition metal oxides (such as ZnO, NiO, CuO, WO3) made with laser ablation in liquid (PLAL) or with low-cost methods such as chemical and hydrothermal bath syntheses , allow to obtain extremely competitive and low environmental impact sensors for applications both in the biomedical field (glucose, pH or DNA sensors) and environmental (for example heavy metal sensors). Particular importance is given to the study and development of combined nanostructured materials (eg bi- or trimetallic clusters) with motion properties relevant for catalysis.
Gas Sensors

Gas sensors are used in sectors ranging from air quality control to food freshness control to the diagnosis of diseases. In particular, the chemoresistive sensors, made mainly with nanostructured semiconductor metal oxides (ZnO, WO3, CuO ...), obtained both with low-cost techniques such as chemical and hydrothermal bath synthesis and with laser ablation in liquid, are characterized by very high sensitivity towards a very large class of gases and vapors (such as NO, CO, H2, NO2, etc.), are very compact and economical and require very little maintenance.
Optical Sensors for biomedical applications
Faculty: M. J. Lo FaroA. A. LeonardiP. MusumeciF. Priolo 
Optical sensors base their operation on the conversion of light rays into an electronic signal. They can be used in many fields ranging from simple distance sensing to biological material sensing allowing versatile, fast, non-destructive and highly sensitive measurements. The combination of the experience in silicon-based photonics and the ability to create such materials in nanostructured form has allowed us to obtain cutting-edge results.
Sensors for textile electronics
FacultyA. A. LeonardiF. Torrisi 
Sensors integrated into the tissues capable of monitoring body parameters, movement or protecting the user from heat and cold are extremely important in the field of health monitoring and protection in the workplace. The research group has developed a state-of-the-art platform of motion, thermal and biochemical sensors that can be printed on fabrics and can be integrated with textile fibers based on two-dimensional materials and biocompatible semiconductor polymers.
