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.

在研究项目中，我们完成了以下七个子课题：(1)研制一种坚固可靠的超灵敏压力传感器，用于非侵入性生物测量。研制的电容式传声器传感器满足生物测量的要求。(2)无线低功耗信号发射机的研制。调频无线发射机的功率为1.5mAx3V，是功率最低的发射机之一。它有效地应用于生物测量。(3)信号处理LSI电路的研制。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)睡眠阶段的非接触估计。提出了一种新的睡眠估计方法，该方法通过气动方法测量的心率和身体运动来估计睡眠阶段。经过40多个晚上的验证，证明了该方法的有效性。(5)患者隐私保护。探讨了如何保护患者隐私的策略。未发现明确的策略。(6)使用生物医学测量方法的患者的心理状态。其主要结果是年轻女性很难接受这种方法，而长辈很容易接受。(7)系统集成。在研究项目中获得的知识被集成到一个由微处理器实现的系统中。该单元可以测量基本的生物信号，并通过提出的新方案来估计睡眠阶段。
