Artery-blocking experiment shows that phase difference of two pulse waves at the same location is well related with blood pressure and blood flow fluctuation. Exercise-recovery experiment resulting from 16 subjects shows that phase difference varies with blood pressure with the correlation from 0.63 to 0.88 when blood pressure changes rapidly. Simulations based on a classic hemodynamic model verify the relationship between phase difference and blood pressure. However, phase difference is strongly correlated with smooth muscle state of the arterial wall as well. If smooth muscle information can be obtained by further study, phase difference can act as a promising approach to portable and wearable device for real-time blood pressure monitoring. <\/jats:p>","DOI":"10.1177\/1550147719837877","type":"journal-article","created":{"date-parts":[[2019,3,22]],"date-time":"2019-03-22T05:21:31Z","timestamp":1553232091000},"page":"155014771983787","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Noninvasive blood pressure estimation with peak delay of different pulse waves"],"prefix":"10.1177","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3867-8741","authenticated-orcid":false,"given":"Yibin","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Microelectronics, Tsinghua University, Beijing, China"}]},{"given":"Shengnan","family":"Li","sequence":"additional","affiliation":[{"name":"CNCERT\/CC, Beijing, China"}]},{"given":"Houbing","family":"Song","sequence":"additional","affiliation":[{"name":"West Virginia University Institute of Technology, Beckley, WV, USA"}]},{"given":"Bin","family":"Shao","sequence":"additional","affiliation":[{"name":"Department of Breast Oncology, Peking University Cancer Hospital & Institute, Beijing, China"}]},{"given":"Xiao","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Software, Tsinghua University, Beijing, China"}]},{"given":"Ning","family":"Deng","sequence":"additional","affiliation":[{"name":"Institute of Microelectronics, Tsinghua University, Beijing, China"}]}],"member":"179","published-online":{"date-parts":[[2019,3,21]]},"reference":[{"doi-asserted-by":"publisher","key":"bibr1-1550147719837877","DOI":"10.1097\/00126097-200408000-00007"},{"doi-asserted-by":"publisher","key":"bibr2-1550147719837877","DOI":"10.1126\/science.6166045"},{"doi-asserted-by":"publisher","key":"bibr3-1550147719837877","DOI":"10.1002\/9781119226444"},{"volume-title":"Cyber-physical systems: foundations, principles and applications","year":"2016","author":"Song H","key":"bibr4-1550147719837877"},{"doi-asserted-by":"publisher","key":"bibr5-1550147719837877","DOI":"10.1161\/01.HYP.25.6.1276"},{"doi-asserted-by":"publisher","key":"bibr6-1550147719837877","DOI":"10.1161\/HYPERTENSIONAHA.107.100727"},{"doi-asserted-by":"publisher","key":"bibr7-1550147719837877","DOI":"10.1161\/01.HYP.36.5.901"},{"volume-title":"Proceedings of the 14th international conference on hybrid intelligent systems (HIS 2014)","author":"Sarv Ahrabi S","first-page":"315","key":"bibr8-1550147719837877"},{"doi-asserted-by":"publisher","key":"bibr9-1550147719837877","DOI":"10.1007\/s00421-011-1983-3"},{"key":"bibr10-1550147719837877","first-page":"5877","volume-title":"Proceedings of the annual international conference of the IEEE engineering in medicine and biology society","volume":"6","author":"Poon C"},{"volume-title":"Proceedings of the 2009 IEEE 3rd international conference on nano\/molecular medicine and engineering","author":"Phua CT","first-page":"112","key":"bibr11-1550147719837877"},{"doi-asserted-by":"publisher","key":"bibr12-1550147719837877","DOI":"10.1109\/RBME.2018.2822301"},{"doi-asserted-by":"publisher","key":"bibr13-1550147719837877","DOI":"10.1109\/TBME.2014.2318779"},{"volume-title":"Proceedings of the 2013 IEEE international symposium on medical measurements and applications (MeMeA)","author":"He X","first-page":"17","key":"bibr14-1550147719837877"},{"volume-title":"Proceedings of the 35th annual international conference of the IEEE engineering in medicine and biology society","author":"Zheng Y","first-page":"6103","key":"bibr15-1550147719837877"},{"doi-asserted-by":"publisher","key":"bibr16-1550147719837877","DOI":"10.1109\/JSEN.2006.874438"},{"doi-asserted-by":"publisher","key":"bibr17-1550147719837877","DOI":"10.1007\/s10439-009-9759-1"},{"volume-title":"Proceedings of the 2005 IEEE engineering in medicine and biology 27th annual conference","author":"Ma T","first-page":"996","key":"bibr18-1550147719837877"},{"doi-asserted-by":"publisher","key":"bibr19-1550147719837877","DOI":"10.1109\/JTEHM.2017.2788885"},{"doi-asserted-by":"publisher","key":"bibr20-1550147719837877","DOI":"10.1007\/s10439-011-0467-2"},{"doi-asserted-by":"publisher","key":"bibr21-1550147719837877","DOI":"10.1161\/01.HYP.0000154229.97341.d2"},{"volume-title":"Proceedings of the 2011 IEEE international instrumentation and measurement technology conference","author":"Joseph J","first-page":"1","key":"bibr22-1550147719837877"},{"volume-title":"Proceedings of the 2014 IEEE region 10 symposium","author":"Samria R","first-page":"254","key":"bibr23-1550147719837877"},{"doi-asserted-by":"publisher","key":"bibr24-1550147719837877","DOI":"10.3390\/s110201784"},{"volume-title":"Proceedings of the 2009 international conference on biomedical and pharmaceutical engineering","author":"Phua CT","first-page":"1","key":"bibr25-1550147719837877"},{"unstructured":"Yuanzhen F.
