Abstract
A sensor for detecting sleep related autonomic nervous system arousals has a PVDF piezo component designed to be affixed to a body part exhibiting arterial pulse wave activity, such as a finger or toe. The signal from the PVDF piezo transducer due to pulse wave activity is signal processed and delivered to a PSG machine or a portable device for stowing digitized waveforms. It is found that the sensor output correlates well with EEG indications of cortical arousals.
