  • Pyro/piezo sensor
    Patent number: 6254545
    Abstract: A combination thermal and vibration sensor for use in sleep monitoring equipment comprises a thin film of a plastic exhibiting both pyroelectric and piezoelectric properties. By providing a layer of foam material totally covering one major surface of the plastic film layer, it is found that the thermal mass of the sensor is changed to the point where the pyroelectric signal can more readily be isolated from the piezoelectric signal using conventional signal processing techniques.
