A telemetry technique and a test-system have been developed to realize continuous vital-sign monitoring for the senior citizens living alone and the patient in home care. The following research has been conducted.1. A ring-type sensor was designed to measure pulse-wave optically without interfering a daily activity of the subject. The telemeter using the ring-type sensor satisfied the practical demands for signal fidelity, transmission range, size, weight and battery life.2. A technique of two-step telemetry was newly devised to meet the antagonizing requirements for low constraint and wide coverage-area at the same time.3. Using a PHS terminal, an ultra-wide area telemonitoring system has been developed to realize the above technique.4. Using the developed system, the practicality and the usefulness of the proposed technique was tested in normal and unfavorable environmental conditions.Through this study, the following results were obtained. A vital-sign can be continuously monitored almost unconsciously. Usually the range of telemonitoring had been confined in a home. With this technique, the range has been expanded to the extent of almost all the domestic areas. A practical technique has been developed to monitor a vital-sign using a wearable common terminal both inside and outside the home. In the home, the cellular phone terminal serves as a cordless phone and no network charge is required. Through the experiments, the feasibility of the proposed technique and the practical usefulness of the developed system were verified.

为了实现对独居老人和家庭护理病人生命体征的连续监测，研制了遥测技术和测试系统。进行了以下研究。1.设计了一种环形传感器，用于光学测量脉搏波，而不干扰受试者的日常活动。采用环形传感器的遥测仪在信号保真度、传输距离、体积、重量和电池寿命等方面满足实际需要.新设计了两步遥测技术，同时满足了低约束和宽覆盖区域的对抗要求。利用PHS终端，开发了一个超广域远程监护系统，实现了上述技术.利用所开发的系统，在正常和不利的环境条件下对所提出的技术的实用性和有效性进行了测试。生命体征几乎可以无意识地持续监测。通常远程监护的范围被限制在一个家庭。通过这项技术，范围已扩大到几乎所有国内地区。已经开发了一种实用的技术来使用可穿戴的公共终端在家庭内外监测生命体征。在家庭中，蜂窝电话终端用作无绳电话，并且不需要网络费用。通过实验验证了该技术的可行性和所开发系统的实用性。
