1. Video Tutorial: Smart Sensors ABSTRACT Smart Sensors are sensing elements enhanced with elaboration and connectivity. They are the key points for distributed architectures and Internet of things. A particular attention should be given to smart sensors for building automation, environment, smart cities, and healthcare (wearable sensors). Thanks to the lower cost of legacy consumer market technologies, mainly Bluetooth, WiFi, ZigBee or subGHz solutions (e.g. WMbus, Z-Wave), smart sensors are spreading and changing our life. Mobile devices (e.g. Smartphones, Tablets) have on board a growing number and type of smart sensors, enabling the easy and fast development of several APPs. Although the quality/cost ratio of these embedded sensors is very good, the metrological performance are often quite poor due to uncertainty introduced by the Operative Systems (e.g. Android callbacks). Another important topic expanding the concept of Smart sensing, especially in environment monitoring applications, is delocalized or “virtual” sensing: the information is locally updated although the source and the location of the measurement is practically unknown. In this tutorial, a brief resume of the main characteristics of smart sensors is proposed, especially in the light of wireless links. The growing importance of smart sensors, especially in Mobiles-based applications, is highlighted and pros and cons, as battery life, are discussed.

Video Tutorial: Smart Sensors Presenter: Alessandra Flammini Dept. of Information Engineering, University of Brescia, 25123-Brescia, ITALY After graduation (1985), Alessandra Flammini was employed in Ansaldo Industria, Milano, working in the Research and Development of Motor Drives. Since 1995, she has been a Researcher in Electronics and since 2016 she has been a Full Professor of Electronic Measurements at the University of Brescia. She is the responsible of the didactic Electronics Laboratory (since 2002) and of the PROFIBUS and PROFINET laboratory (since 2004 to 2013). Her research activity mainly deals with: electronic instrumentation and digital processing of sensor signals; sensor networks and Real- Time Ethernet; wireless sensor networks based on different technologies, smart grids, body sensors. Manager of the Research Group of Embedded Systems and Smart Sensors (two Associate Professors, two Researchers), she is now working at five financed projects about Smart cities. Member of IEEE1588 Study Group and of the ADCOM of IEEE-IMS, she has been the Chair of many international Conferences. She is the author of more than 200 international papers (scientific journals, conference proceedings patents).
