Utilizzo di MEMS per il monitoraggio strutturale

Structural Health Monitoring (SHM) is a filed that take advantage of the unprecedented development of sensor, microelectronics and microprocessor technologies. The new generation of SHM systems are based on MEMS (Micro Electro-Mechanical Systems) and relies on designs that integrate advanced sensor technologies with distributed computational power as well as efficient implementation of identification methodologies to realize “intelligent” sensors that elaborate local models and exchange data, information and models on a local network managed by a control/storage unit usually accessible also in a remote way. The purpose of this paper is to describe the results obtained from a MEMS-based sensing system starting from accelerations measured from a laboratory prototype and the preliminary analysis of the dynamic behavior of the tower of the Faculty of Engineering in Bologna. The results are shown comparing the MEMS based sensing system with a traditional system.
