Application of MEMS to monitoring system for natural disaster reduction

Recently it has become important to develop a new monitoring system for structures. This is because the ageing infrastructure and an increase in abnormal weathers caused by the climate change have resulted in hazard assessments becoming more difficult. Therefore, there is a need to be able to monitor vulnerable structures more carefully and to assess their safety in real time. For this purpose, we require a new monitoring system that can monitor a structure more closely, easily, and efficiently than the existing methods. We developed a new monitoring system using a Micro Electro Mechanical System and wireless communication. We applied this system to a retaining wall with a deep-seated slope failure, in order to assess the serviceability of this method in general, and the safety of this retaining wall in particular.
