| Outline of Final Research Achievements |
The proposing respiratory sensor measuring the body impedance is analyzed in the frequency characteristics, and the following things are found. The impedance is nearly capacitive and its value is decided around the skin, and the capacitance itself changes with the respiration. The gap of the electrical thickness of the skin is considered to be the main factor which causes the change synchronous with the respiratory cycle. Based on these founding, the electrode which contacts with the skin is introduced for obtaining the pure signal avoiding the artificial noise. When the pasting condition becomes stable, the long-time measurement can detect the minute change of the body filling due to the eating as the capacitance increase. The respiration is measured during the exercising. Although the noise increases, the patients’ respiration signal can be obtained during walking, running, twisting, and bending.
