We developed a compact and low cost ultra wideband noise sensor for medical diagnostics and vital sign monitoring in pre-hospital settings. In this work, we demonstrated the functionality of the sensor for respiration and heartbeat monitoring. In the test, metronome was used to manipulate the breathing pattern and the heartbeat rate reference was obtained with a commercial electrocardiogram (ECG) device. With seventeen tests performed for respiration rate detection, sixteen of them were successfully detected. The results also show that it is possible to detect the heartbeat rate accurately with the developed sensor.<\/jats:p>","DOI":"10.3390\/s20041034","type":"journal-article","created":{"date-parts":[[2020,2,20]],"date-time":"2020-02-20T03:20:03Z","timestamp":1582168803000},"page":"1034","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Investigation of an Ultra Wideband Noise Sensor for Health Monitoring"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6606-0386","authenticated-orcid":false,"given":"Xuezhi","family":"Zeng","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Chalmers University of Technology, SE412-96 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joakim","family":"Robakowski","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Chalmers University of Technology, SE412-96 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikael","family":"Persson","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Chalmers University of Technology, SE412-96 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6086-9328","authenticated-orcid":false,"given":"Albert","family":"Monteith","sequence":"additional","affiliation":[{"name":"Department of Space, Earth and Environment, Chalmers University of Technology, SE412-96 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9858-1688","authenticated-orcid":false,"given":"Andreas","family":"Fhager","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Chalmers University of Technology, SE412-96 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13","DOI":"10.2310\/8000.2011.100232","article-title":"Patient safety in emergency medical services: Executive summary and recommendations from the Niagara summit","volume":"13","author":"Bigham","year":"2011","journal-title":"Can.
