The newly developed low-cost micro-electro-mechanical system (MEMS)-based acceleration sensors exhibit sufficient accuracy and stability to monitor the shaking of structures caused by an earthquake. We have developed a practical shaking-monitoring system using MEMS-based acceleration sensors and a 920 MHz multi-hop radio communication method that offers reliable radio wave communication, even within buildings. In this system, the base clock of each sensor unit must be closely synchronized to the master clock to minimize acceleration-induced phase synchronization error. In the proposed system, this error can be limited to three milliseconds in a system of multiple sensor units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
