Abstract

Abstract:

Tongue pressure and its contact stress on the hard palate are the important investigation objects for the human's phonation rectification and dental arch growth. The purpose of this thesis is to build a measurement system in order to measure the intraoral pressure in human's mouth during speaking and swallowing.

A PC real-time measuring system with micro pressure sensor is well suited for testing the pressure in the human's mouth. A suitable pressure sensor is chosen by the requirement. Through water protection, sensor can operate on the temperature in human's oral cavity. It is incorporated with Flexible Print Circuit Board (FPCB) and fixed on a palatal plate formed of thermoplastic.

To shield the sensor from saliva effectively, the various experimental tests including measurements of characteristics line, systematic errors and water proof ability were necessary to be done respectively. The successful tests show that the application silicone is a good way for making water protection.

The self-test of intraoral pressure is measured at rest and during swallowing, speaking situation. The generated electrical signal from sensor is amplified by a produced signal conditioning circuit into 100 times larger enough to be captured by the data acquisition card (DAQ) and then analyzed by programming in LabVIEW. Here, the output voltage at rest situation as offset compensation has been set up.

Finally, the results of the contact pressure during tongue motion are represented in this thesis. They show that the mean maximal pressure during swallowing is 136.49 mbar, and the mean maximal pressure during speaking is 282.33mbar.
