Special Session 10

Calibration and metrological characterization of digital sensors and sensor network, based on MEMS/NEMS technology, is a metrological challenge, due to the lack of Standards, conformity of technical procedures, and proper sensitivity parameters of digital sensors.
Nevertheless, MEMS sensors and network are largely used in industrial processes controls (e.g. by monitoring performance degradation for defects prevention, or managing the automation), as well as for many other applications, such as environmental, seismic and infrastructures survey, navigation and positioning systems, remote surgery and diagnoses, health feedback survey and environmental/natural hazard.
In these applications, data quality is of paramount importance, in particular for managing big data and data aggregation in extensive sensor networks. Data quality assessment of sensor networks depends on traceable calibration of digital sensors in nodes, metrological treatment of sensor network as a whole, remote self-calibration, data fusion in network systems and the overall uncertainty budget management.
