Beschreibung
Zusammenfassung:	The authors developed a new type of smart vibration sensor, which consists of a MEMS tri-axial accelerometer and a micro-processor on board with wireless data transmission unit. The sensor is characterized by converting acceleration data into several indices on board, which are transmitted via power saving wireless standard; ZigBee. Through the two experiments, one was to verify dynamic properties of the accelerometer and another was to confirm data transmissibility in an actual building, it was confirmed that the smart sensor could be the key component for practical structural health monitoring system, such as global monitoring system by detecting the change in dynamic properties of building structures.
