Nursing and Support by the Non-restraint Health Monitoring System

在研究项目中，我们处理了以下七个子项目；(1)研制一种鲁棒可靠的超灵敏压力传感器，用于无创生物测量。所研制的电容式传声器传感器满足生物测量的要求。(2)无线低功率信号发射机的研制。FM无线发射机功耗为1.5mAx3V，是功率最小的发射机之一。它有效地应用于生物测量。(3)开发用于信号处理的大规模集成电路。设计并研制了一种用于信号处理的新型多功能集成电路。采用了轨对轨、旋转器和新技术进行开发。(4)睡眠阶段的非接触估计。提出了一种新的睡眠估计方法，通过测量心率和身体运动来估计睡眠阶段。在40多个晚上进行的诽谤测试证明了该方法的有效性。(5)保护患者隐私。研究了如何保护患者隐私的策略。没有找到明确的策略。(6)使用所提出的生物医学测量方法的患者心理状态。主要结果是年轻女士很难接受这种方法，而老年人很容易接受。(7)系统集成。在研究项目中获得的知识被集成为一个由微处理器实现的系统。该装置可以测量基本的生物信号并估计睡眠阶段。

In the research project, we treated the following seven sub-projects;(1) Development of a robust and reliable supersensitive pressure sensor for the non-invasive bio-measurement. The condenser-microphone based sensor developed satisfies the specifications required for the bio-measurement.(2) Development of a wireless low powered signal transmitter. The FM wireless transmitter consumes the power of 1.5mAx3V which is one of the minimum powered transmitters. It is effectively applied to the bio-measurement.(3) Development of an LSI circuit for signal processing. A novel multi-functional LSI for the signal processing was designed and developed. The rail to rail, gyrator and new technology were employed for the development.(4) Non-contact estimation of the sleep stage. Novel sleep estimation was presented, which estimates the sleep stage by the heart rate and body movements measured by the proposed pneumatic method. The vilification tests carried out over 40 nights demonstrated the validity of the method.(5) Protection of the privacy of the patients. Strategies how to protect the privacy of patients were investigated. The clear strategy was not found.(6) Psychological states of patients who use the proposed bio-medical measurement methods. The key results are the young ladies hardly accept the method, whereas the elders easily accept it.(7) System integration. The knowledge obtained in the research project is integrated as a system realized by a micro-processor. The unit can measure the basic bio-signals and estimate the sleep stages by the proposed novel scheme.
