Anahtar Kelimeler:Directional condenser microphone,Pressure pulse wave meter,Correlation coefficient

Özet: This paper describes a novel sensor device, a pressure pulse wave meter, which uses a directional condenser microphone. Currently aging is becoming a serious social issue in Japan causing increased medical expenses in the country. It seems important for elderly citizens to check health condition at home, and to care the health conditions through daily monitoring. Given this circumstances, we developed a novel pressure pulse wave meter based on a directional condenser microphone: this device is used as a measuring instrument of health conditions of living bodies. The wave meter results showed the wave forms measured from the pressure pulse wave meter and those from photoelectric sphygmograph were quite similar; the correlation coefficient was 1.0.
