| Research Abstract |
As part of a research and development of bed-type non-intrusive cardiopulmonary monitor for home-healthcare applications in daily use, we conducted the followings : (a) examination of effects of frequency pass band of band-pass filter on signal quality during overnight measurement, (b) development of digital inverse filter which recovers low frequency components damped by analog high pass filter, and accuracy validation of QT interval which was estimated from the recovered ECG signal, (c) development of a real-time system to reduce power-line noise and its harmonics in measured signal, (d) invention of framework to measure two ECG signals and two breathing activities simultaneously using three electrodes placed under a bed-sheet, (e) fabrication of novel sensing circuits to detect absence/existing and lying body postures.
