Abstract
In the domain of intraoral hydration sensing to monitor oral health, there is sparse research on continuous capacitive sensing. Most devices can only perform a single point of measurement, making it unsuitable for wearing long-term. This paper aims to research the possibility of expanding the Densor developed by Dsouza et al. [4], with a capacitive sensor to measure hydration in the mouth, by testing it on NaCl-demineralised water solutions. The obtained data does not yet show any strong correlation between salt values and measured values, suggesting the sensor might not be suitable for this purpose, but the data is yet insufficient to draw any definite conclusions.
