Nursing and Support by the Non-restraint Health Monitoring System

在本研究项目中，我们主要进行了以下七个子项目的研究：（1）研制一种用于无创生物测量的高灵敏度压力传感器。基于电容传声器的传感器满足生物测量所需的规格。(2)一种无线低功耗信号发射机的研制。FM无线发射机的功耗为1.5mAx3V，是最低功耗的发射机之一。该方法有效地应用于生物测量。(3)开发用于信号处理的LSI电路。设计并研制了一种新型多功能信号处理大规模集成电路。研制中采用了轨对轨、回转器和新技术。(4)睡眠阶段的非接触式估计。提出了一种新的睡眠估计方法，该方法通过所提出的气动方法测量的心率和身体运动来估计睡眠阶段。经过40多个夜晚的实验验证了该方法的有效性。(5)保护患者的隐私。探讨了如何保护患者隐私的策略。没有找到明确的战略。(6)使用所提出的生物医学测量方法的患者的心理状态。关键的结果是年轻女士很难接受这种方法，而老年人很容易接受它。(7)系统集成。在研究项目中获得的知识被集成为一个系统，由微处理器实现。该单元可以测量基本的生物信号和估计的睡眠阶段所提出的新方案。

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.
