Exploiting Persistent Vibration Phenomena and MEMS Conversion Effects at the Castello Ursino Museum (Sicily, Italy)

This paper explores persistent vibration phenomena measured at the Castello Ursino Museum in Catania and their effects, analyzed through Aluminum Nitride (AlN) Micro-Electro-Mechanical Systems (MEMS) transducers. The study aims to utilize the Tromino® measurement system to assess the structural dynamics and vibration behavior of the museum. By analyzing vibration data, the research identifies areas with persistent vibrations that can serve as optimal sites for placing MEMS sensors, thereby maximizing energy harvesting for autonomous monitoring. Through damping analysis, the study highlights regions within the museum, particularly the primary Pinacoteca Room on the second level, where vibrations are most significant. These vibrations are attributed to factors such as structural dynamics, visitor movement, and nearby traffic. While these areas offer potential for increased energy capture, it is also essential to monitor high levels of vibration, as they can be potentially critical for the conservation of artifacts. Measurement campaigns conducted both in the laboratory and on-site demonstrate the feasibility of this approach for applications in cultural heritage sites and environments of historical and artistic interest. This research contributes to the development of energy-efficient, autonomous solutions, advancing the preservation and monitoring of culturally significant and architecturally complex sites such as the Castello Ursino Museum.
