This research aimed to study and develop a proposal for an integrated system that combines IoT, data analysis, AR and VR for the monitoring and maintenance of industrial equipment. The importance of this research lies in its potential to contribute to the implementation of predictive maintenance solutions, which can significantly reduce machine downtime in an industrial environment and thus reduce or prevent operational failures. The central research question of this work was the following: how can the integration of IoT, data analysis and augmented and virtual reality contribute to optimizing industrial maintenance? We tested the combination of technologies to enable the creation of an effective predictive maintenance system, capable of alerting operators to anomalous conditions and providing detailed visual instructions for maintenance tasks. As a result, a prototype system was developed and tested, and it has shown the potential to evolve into a real system in an industrial environment.<\/jats:p>","DOI":"10.3390\/s25030845","type":"journal-article","created":{"date-parts":[[2025,1,30]],"date-time":"2025-01-30T11:42:37Z","timestamp":1738237357000},"page":"845","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Smart Maintenance Solutions: AR- and VR-Enhanced Digital Twin Powered by FIWARE"],"prefix":"10.3390","volume":"25","author":[{"given":"Andr\u00e9","family":"Costa","sequence":"first","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"}]},{"given":"Jo\u00e3o","family":"Miranda","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"}]},{"given":"Duarte","family":"Dias","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"}]},{"given":"Nuno","family":"Dinis","sequence":"additional","affiliation":[{"name":"RIOPELE, 4770-405 Vila Nova de Famalic\u00e3o, Portugal"}]},{"given":"Lu\u00eds","family":"Romero","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"}]},{"given":"Pedro Miguel","family":"Faria","sequence":"additional","affiliation":[{"name":"IPVC\u2014Instituto Polit\u00e9cnico de Viana do Castelo, 4900-347 Viana do Castelo, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,30]]},"reference":[{"key":"ref_1","unstructured":"Mihai, S., Davis, W., Hung, D., Trestian, R., Karamanoglu, M., Barn, B., Prasad, R., Venkataraman, H., and Nguyen, H.
