In this work, contrary to conventional radar\u2010based sensing and WiFi\u2010based setups which require line\u2010of\u2010sight (LoS) to process and collect the RF signals for monitoring, it is shown for the first time in literature the potential of using RF sensing for vitals, that is, heartbeat detection in the non\u2010line\u2010of\u2010sight (NLoS) using an in\u2010house\u2010developed reconfigurable intelligent surface (RIS), that is, wireless on the walls. The developed RIS is the world's first prototype which consists of \u201c4096 elements\u201d. The unit cell elements are individually controlled via PIN diodes, 1\u2010bit, operating at 3.75\u2009GHz specified for the fifth\u2010generation (5G) network. Near\u2010field beam steering is demonstrated, with a switching speed of 15\u2009ms. For the first time in the literature its is demonstrated that RIS can assist in the detection of microactivities including the human heartbeat in NLoS indoor complex environment, a limitation with the existing RF sensing technologies to date. In addition, it is experimentally verified that the RIS can potentially reduce the e\u2010field magnitude at the user's by regulating the gain at the user terminal.<\/jats:p>","DOI":"10.1002\/aisy.202300007","type":"journal-article","created":{"date-parts":[[2023,7,8]],"date-time":"2023-07-08T06:29:29Z","timestamp":1688797769000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["In\u2010Home Monitoring Using Wireless on the Walls for Future HealthCare: Real\u2010World Demonstration"],"prefix":"10.1002","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0319-0818","authenticated-orcid":false,"given":"Jalil ur Rehman","family":"Kazim","sequence":"first","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahsen","family":"Tahir","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"},{"name":"Department of Electrical Engineering University of Engineering and Technology  Lahore 54890 PK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Rains","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tie Jun","family":"Cui","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Millimetre Waves Southeast University  Nanjing 210096 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdul","family":"Jabbar","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad Ali","family":"Jamshed","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masood","family":"Ur-Rehman","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akram","family":"Alomainy","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering and Computer Science Queens Mary University of London  London E1 4NS UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad Ali","family":"Imran","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qammer H.","family":"Abbasi","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,7,8]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2018.2872781"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2019.1900271"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2021.3130030"},{"key":"e_1_2_10_5_1","unstructured":"M.Giordani M.Polese M.Mezzavilla S.Rangan M.Zorzi arXiv:1903.12216 2019."},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.2019.1800430"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.001.1900287"},{"key":"e_1_2_10_8_1","unstructured":"F.Tariq M.Khandaker K.-K.Wong M.Imran M.Bennis M.Debbah arXiv:1902.06700 2019."},{"key":"e_1_2_10_9_1","first-page":"167","volume-title":"Toward 6G: A New Era of Convergence","author":"Martin M.","year":"2021"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.005.2100142"},{"key":"e_1_2_10_11_1","first-page":"105","author":"Cao J.","year":"2014","journal-title":"IEEE Comp.
