The sensor is designed and engineered to be embedded inside concrete or masonry structures, like bridges or buildings. It provides good accuracy, robustness, and simplicity of use at potentially low cost for large-scale applications in civil structures. Moreover, it can be calibrated temperature compensated, and it is inherently hermetic, ensuring the protection of sensitive elements from the external environment. It is, therefore, suitable for operating in harsh and dirty environments like civil constructions. The sensor directly measures the internal stress of the structure, exploiting the piezo resistivity of thick film ink based on ruthenium oxide. It is insensitive with respect to the stiffness of the embedding material and the variation of the surrounding material properties like concrete hardening, shrinkage, and creep as it decouples the two components of stress.<\/jats:p>","DOI":"10.3390\/s24020599","type":"journal-article","created":{"date-parts":[[2024,1,17]],"date-time":"2024-01-17T10:39:47Z","timestamp":1705487987000},"page":"599","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Ceramic Stress Sensor Based on Thick Film Piezo-Resistive Ink for Structural Applications"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1380-859X","authenticated-orcid":false,"given":"Gabriele","family":"Bertagnoli","sequence":"first","affiliation":[{"name":"Department of Structural, Geotechnical and Building Engineering (DISEG), Politecnico di Torino, Corso Duca degli Abruzzi, 24, 10129 Turin, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4714-4306","authenticated-orcid":false,"given":"Mohammad","family":"Abbasi Gavarti","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Politecnico di Milano, Via La Masa, 34, 20156 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0708-5580","authenticated-orcid":false,"given":"Mario","family":"Ferrara","sequence":"additional","affiliation":[{"name":"Department of Structural, Geotechnical and Building Engineering (DISEG), Politecnico di Torino, Corso Duca degli Abruzzi, 24, 10129 Turin, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,17]]},"reference":[{"key":"ref_1","unstructured":"Cusatis, G., Alnaggar, M., D\u2019Ombrasia, M., and Qu, J.
