In this respect, micro-electrical mechanical system (MEMS) sensors are widely used in several applications, including structural health monitoring (SHM), in which accelerometric samples are acquired to perform modal analysis. Thanks to their significantly lower cost, ease of installation in the structure, and lower power consumption, they enable extensive, pervasive, and battery-less monitoring systems. This paper presents an innovative high-performance device for SHM applications, based on a low-noise triaxial MEMS accelerometer, providing a guideline and insightful results about the opportunities and capabilities of these devices. Sensor nodes have been designed, developed, and calibrated to meet structural vibration monitoring and modal identification requirements. These components include a protocol for reliable command dissemination through network and data collection, and improvements to software components for data pipelining, jitter control, and high-frequency sampling. Devices were tested in the lab using shaker excitation. Results demonstrate that MEMS-based accelerometers are a feasible solution to replace expensive piezo-based accelerometers. Deploying MEMS is promising to minimize sensor node energy consumption. Time and frequency domain analyses show that MEMS can correctly detect modal frequencies, which are useful parameters for damage detection. The acquired data from the test bed were used to examine the functioning of the network, data transmission, and data quality. The proposed architecture has been successfully deployed in a real case study to monitor the structural health of the Marcus Aurelius Exedra Hall within the Capitoline Museum of Rome. The performance robustness was demonstrated, and the results showed that the wired sensor network provides dense and accurate vibration data for structural continuous monitoring.<\/jats:p>","DOI":"10.3390\/s24082435","type":"journal-article","created":{"date-parts":[[2024,4,11]],"date-time":"2024-04-11T03:29:04Z","timestamp":1712806144000},"page":"2435","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Developing and Testing High-Performance SHM Sensors Mounting Low-Noise MEMS Accelerometers"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2190-1866","authenticated-orcid":false,"given":"Marianna","family":"Crognale","sequence":"first","affiliation":[{"name":"Department of Structural and Geotechnical Engineering, Sapienza University of Rome, Via Eudossiana 18, 00184 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4178-1467","authenticated-orcid":false,"given":"Cecilia","family":"Rinaldi","sequence":"additional","affiliation":[{"name":"Department of Structural and Geotechnical Engineering, Sapienza University of Rome, Via Eudossiana 18, 00184 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2862-9930","authenticated-orcid":false,"given":"Francesco","family":"Potenza","sequence":"additional","affiliation":[{"name":"Department of Engineering and Geology, University \u201cG. d\u2019Annunzio\u201d of Chieti-Pescara, Viale Pindaro 42, 65127 Pescara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5336-3687","authenticated-orcid":false,"given":"Vincenzo","family":"Gattulli","sequence":"additional","affiliation":[{"name":"Department of Structural and Geotechnical Engineering, Sapienza University of Rome, Via Eudossiana 18, 00184 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Colarieti","sequence":"additional","affiliation":[{"name":"West Aquila S.r.l., S.S. 17 snc c\/o Tecnopolo d\u2019Abruzzo, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9558-5344","authenticated-orcid":false,"given":"Fabio","family":"Franchi","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Computer Science and Mathematics, Universit\u00e0 degli Studi dell\u2019Aquila, Via Vetoio, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Preethichandra, D., Suntharavadivel, T., Kalutara, P., Piyathilaka, L., and Izhar, U.
