Evaluation Using a Bidirectional Microphone as a Pressure Pulse Wave Meter
This paper describes a novel sensor device, a pressure
pulse wave meter, which uses a bidirectional condenser microphone.
The microphone work as a microphone as well as a sensor with high
gain over a wide frequency range; they are also highly reliable and
economic. Currently aging is becoming a serious social issue in Japan causing
increased medical expenses in the country. Hence, it is 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
bidirectional condenser microphone: this device is used as a measuring
instrument of health conditions.
