Research Abstract

Sensors and electrodes for a physiological information are important in a biomedical measurement and patient monitoring. Accompanied with a recent development of electronic and mechanical engineering and biomedical meterials, then the technological standard reaches even an expensive level, therefore, small-sized and a high performance and a long stable sensor electrodes are increasingly developed. However, regarding for practical usefulness is comparatively a few. With this research, as foot for to realize a more expensive quality of physiological measurement, we will try about a dissolution of complexity on a lead line to a measuring and recording system from sensors.
We were based on the following research plan, and tried a development of a cableless sensor.
1.We tried about an actualization of cableless sensor. It is wireless sensor in that no lead connects between electrodes and recording unit using short-range telemetry.
2.At various physiological information of cableless sensor, we performed an examination about size, shape, weight, measuring time, stabilization and convenience of a wear for subject.
3.To understand a power and a directivity and so on of a radiation energy of a transmission signal with the sensor built as a trial, we measured an electric field intensity and a practical valid limit of a transmitting distance. Furthermore, to use short-range telemetry, we aimed at making up of telemetry system of a long life with a low consumption power depending on cutting down of a radiation energy from an antenna.
4.We performed an examination about a useful possibility as considering a body as a part of an antenna. Because the quality of the meterial isn't a complete conductor in a body, as assuming an electric model of body, we analyzed on a condition of an antenna shape and an impedance matching.
