| Outline of Final Research Achievements |
To prevent harmful influences on teeth and jaws and unpleasant noises of sleep bruxism (teeth grinding while asleep), development of a suppression system that incorporated the phenomenon of increasing heart rate just before the onset of teeth grinding was investigated. Suppression effect has been confirmed by an experimental system with electrodes for measuring pulse rate and applying electric stiulation. In this study, the meaurement of pulse rate from outside of the body was investigated.
A wearable sensor, a mat-shaped sensor and microphones were tested, and we found unignorable delay due to noise elimination process or incapability of pulse signal extraction from noisy data source. Instant determination of pulse rate fluctuation from outside the body seemed to be difficult at the present time. Re-evaluation of electrodes with less burden on user was made, and a wireless system of pulse rate mesurement was developed.
