碩士 === 國立交通大學 === 電控工程研究所 === 106 === Individualized medical health care is the trend of medical development, especially in the wearable and non-invasive physiological sensing applications. Although personal medical devices which can monitor one’s heart rate and blood pressure have been popular and available to people, sphygmomanometers still cause uncomfortableness and haven’t been improved until now. Therefore, an accurate and comfortable personal medical device is necessary to be developed. From reasons above, this thesis develops a novel evaluation platform based on optical assessment methods, which employ different absorption and scattering properties to specific wavelengths of light in human tissue to obtain blood pressure. Moreover, this thesis proposes a new method that extracts the photoplethysmography (PPG) feature to acquire the blood pressure more accurately. The digital circuit designed from platform algorithm accomplished by Taiwan Semiconductor Manufacturing Company (TSMC) 0.18 μm process. People only need to measure on their hand in order to monitor their personal physiological information, which performs the combination of convenient and health.
