For size reduction, a switching method is proposed in order to use the same frequency band for both supplying power to the nodes and wirelessly transmitting the nodes\u2019 data. A rectenna harvests the electromagnetic energy delivered by the dedicated radiofrequency source for charging a few-mF supercapacitor. For supercapacitors of 7 mF, it is shown that the proposed autonomous sensor nodes were able to wirelessly communicate with the reader at 868 MHz for 10 min without interruption for a tag-to-reader separation distance of 1 meter. This result was obtained from effective radiated powers of 2 W during the supercapacitor charging and of 100 mW during the wireless data communication.<\/jats:p>","DOI":"10.3390\/s19153330","type":"journal-article","created":{"date-parts":[[2019,7,29]],"date-time":"2019-07-29T11:20:18Z","timestamp":1564399218000},"page":"3330","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Autonomous RFID Sensor Node Using a Single ISM Band for Both Wireless Power Transfer and Data Communication"],"prefix":"10.3390","volume":"19","author":[{"given":"Abderrahim","family":"Okba","sequence":"first","affiliation":[{"name":"LAAS-CNRS, Universit\u00e9 de Toulouse, CNRS, INSA, UPS, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominique","family":"Henry","sequence":"additional","affiliation":[{"name":"LAAS-CNRS, Universit\u00e9 de Toulouse, CNRS, INSA, UPS, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandru","family":"Takacs","sequence":"additional","affiliation":[{"name":"LAAS-CNRS, Universit\u00e9 de Toulouse, CNRS, INSA, UPS, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Herv\u00e9","family":"Aubert","sequence":"additional","affiliation":[{"name":"LAAS-CNRS, Universit\u00e9 de Toulouse, CNRS, INSA, UPS, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"52","DOI":"10.1109\/MIC.2016.124","article-title":"Internet of Things for Smart Cities: Interoperability and Open Data","volume":"20","author":"Ahlgren","year":"2016","journal-title":"IEEE Internet Comput."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1109\/MIM.2010.5669608","article-title":"Structural Health Monitoring of Bridges Using Wireless Sensor Networks","volume":"13","author":"Harms","year":"2010","journal-title":"IEEE Instrum.
