| Research Abstract |
In this research, I developed the new impedance moisture sensor for oral measurement, at a stage prior to fabricating the oral optic-fiber moisture meter. About an electrical resistance-type sensor, I produced a flexible film sensor of 45mm in height 12mm in width thickness 0.05mm by using the magnetron sputtering method for a PET sheet. I enabled the impedance measurement with the AC power supply using a root canal meter for a measurement system for dentistry. By the basic characteristic measurement, the change of the impedance wave pattern depending on quantity of water was provided, and the possibility about detecting the mucous membrane moisture in the oral cavity was suggested. In addition, I experimentally produced the device which enabled the simultaneous measurement of the humidity and moisture measurement in the oral cavity.
