Enhanced accelerometer for structural health monitoring

Structural Health Monitoring (SHM) plays a crucial role in conserving and safeguarding the world's patrimony of historical buildings. Indeed, it allows, on the one hand, understanding the dynamic behavior of the structures in question, and on the other, checking their health status in real time. Obviously, application of such systems in the field of cultural heritage calls for employing low-cost technologies that enable non-invasive monitoring under in-service conditions. This paper describes a wireless SHM system based on a low-cost 3-axis accelerometer and the frame structure used for its calibration.
