Summary: | 碩士 === 國立臺灣大學 === 電機工程學研究所 === 88 === A spirometric system can be used to determine static and dynamic lung function for diagnosis, therapy and evaluation. In recent years, air pollution and deteriorating environment cause respiratory diseases increasing rapidly. A portable spirometric system, which aims for home care and possible screening test in hospital is the answer to this need. This thesis will address the issues of system design, which contains microsensor, preamplifier, micro-controller and LabVIEW algorithm for signal analysis. By improving the flow sensor and system design, we will try to overcome the accuracy problems of currently used sensors.
Recently, the established technologies of microelectromechanical system (MEMS) have enabled the possible minimization of spirometer with microsensor. It includes the modular design for low power consumptions, precision volume productions, competitive price for disposable sensors. In this thesis, the focus is to improve sensor’s performance by using MEMS technologies. The use of American Thoracic Society (ATS) guideline for system implementation assures the quality of system for future upscale production of safe and quality device.
