Wearable sensors for cardiovascular monitoring
One of the most popular wearable devices is a pulse rate (PR) monitor using photoplethysmography (PPG), which was first introduced in the late 1930s as an optical and non-invasive method used to detect volume changes in blood vessels. PPG provides information on the cardiovascular system, particularly pulse and respiratory rates. Currently, cardiovascular disease is the most morbidity-related disease following cancer. Blood pressure plays an especially important role in maintaining health. Applying PPG technology, cuffless blood pressure monitor has been attempted worldwide because of its wearability, easy to handle and low cost. In this presentation the wearable cardiovascular monitors are reviewed, and possibility of clinical practice are discussed.
Dr. Toshiyo Tamura (S75-M81-SML15) received his Ph.D. from Tokyo Medical and Dental University in 1980. He is currently a Visiting Professor, Future Robotics Organization, Waseda University, Japan. His research interests include biomedical instrumentation, biosignal processing, telemedicine telecare, home care technology and rehabilitation engineering. His and his colleagues’ book entitled “Biomedical sensors and instruments” and “Seamless healthcare monitoring” are popular textbooks for bioinstrumentation and medical devices. He also wrote several chapters including sensors for telemedicine and application of wearable inertia sensors. He has served as a chair of the Asian Pacific representative for the IEEE/EMBS from 2000 to 2004. He is fellows of IAMBE and Japanese Society of Medical Electronics and Biological Engineering.
