概要

The drowsy driving arisen from fatigue has come to be a social problem. As a preventive means of this situation, some systems which catch drowsiness and sleep prediction by detecting a driver's biological signals are proposed. However, there are few reports about noninvasive biological signal sensing devices. This is so that biological signals are buried in mechanical vibration input to a car. This sensing system consists of the air pack generating pressure, the condenser type microphone sensor detecting pressure and signal processing circuit part. The detected breathing and pulse wave took correlation with an optical finger plethysmogram measurement device.
