The system is self-powered from bus bars, and features wireless communication and easy-to-access information and alarms. With cell voltage and electrolyte temperature measurements, the system enables real-time cell performance discovery and early reaction to critical production or quality disturbances such as short-circuiting, flow blockages, or electrolyte temperature excursions. Field validation shows an increase in operational performance of 30% (reaching 97%) in the detection of short circuits, which, thanks to a neural network deployed, are detected, on average, 10.5 h earlier compared to the traditional methodology. The developed system is a sustainable IoT solution, being easy to maintain after its deployment, and providing benefits of improved control and operation, increased current efficiency, and decreased maintenance costs.<\/jats:p>","DOI":"10.3390\/s23052517","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T03:37:20Z","timestamp":1677209840000},"page":"2517","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Battery-Less Industrial Wireless Monitoring and Control System for Improved Operational Efficiency"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2307-0031","authenticated-orcid":false,"given":"Eduardo","family":"Hidalgo-Fort","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, University of Seville, 41092 Seville, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1304-8372","authenticated-orcid":false,"given":"Juan Antonio","family":"G\u00f3mez-Gal\u00e1n","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Computers, and Automation, University of Huelva, 21007 Huelva, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ram\u00f3n","family":"Gonz\u00e1lez-Carvajal","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, University of Seville, 41092 Seville, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro","family":"S\u00e1nchez-C\u00e1rdenas","sequence":"additional","affiliation":[{"name":"Atlantic Copper S.L.U.
