Still, in order to enhance the usability as well as reduce the sensor cost, researchers endeavor to establish a generalized BP estimation model using only PPG signals. In this paper, we propose a deep neural network model capable of extracting 32 features exclusively from PPG signals for BP estimation. The effectiveness and accuracy of our proposed model was evaluated by the root mean square error (RMSE), mean absolute error (MAE), the Association for the Advancement of Medical Instrumentation (AAMI) standard and the British Hypertension Society (BHS) standard. Experimental results showed that the RMSEs in systolic blood pressure (SBP) and diastolic blood pressure (DBP) are 4.643 mmHg and 3.307 mmHg, respectively, across 9000 subjects, with 80.63% of absolute errors among estimated SBP records lower than 5 mmHg and 90.19% of absolute errors among estimated DBP records lower than 5 mmHg. We demonstrated that our proposed model has remarkably high accuracy on the largest BP database found in the literature, which shows its effectiveness compared to some prior works.<\/jats:p>","DOI":"10.3390\/s20195668","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T08:35:57Z","timestamp":1601886957000},"page":"5668","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":75,"title":["Generalized Deep Neural Network Model for Cuffless Blood Pressure Estimation with Photoplethysmogram Signal Only"],"prefix":"10.3390","volume":"20","author":[{"given":"Yan-Cheng","family":"Hsu","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, National Central University, Taoyuan 32001, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0475-3689","authenticated-orcid":false,"given":"Yung-Hui","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Central University, Taoyuan 32001, Taiwan"}]},{"given":"Ching-Chun","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Tsing Hua University, Beijing 100084, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1141-1406","authenticated-orcid":false,"given":"Latifa Nabila","family":"Harfiya","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Central University, Taoyuan 32001, Taiwan"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,4]]},"reference":[{"key":"ref_1","unstructured":"WHO (2019, May 01).
