Development of the pH measurement sensor to be mounted on the oral measurement device

Health management indicator of athletes have been proposed. Not widely penetrate the athlete. The measurement method is blood tests and POMS test. But, There is a disadvantage to the measurement method. blood tests difficult to early acquisition of the results and POMS test is not a physiological indicator. Current, Saliva is attracting attention because saliva can be noninvasively collect. Therefore, There is a need for a new method of using a saliva. So, Currently, intraoral measurements are performed in the denture type pH sensor. However, the oral cavity is secretions are different depending on the site. It requires the development of a wide range of measurement device capable. So, I make pH measurement sensor to be mounted on the mouthpiece device. pH measurements in the oral cavity is performed by the existing method. The oral cavity is required multi point measured. However, it is not possible to measure the entire mouth. Use of a new Ag/AgIO
3
measurement method was tried in the laboratory. This method mimics the antimony electrode method. This method uses the antimony electrode and Ag/AgIO
3
electrode. The measurement method is capable of a wide range of measurement. This electrodes required for the measurement. It is forming a Ti and Ag/AgIO
3
by sputtering. Sputtering was employed RF magnetron sputtering. This method can be applied in insulator. Measuring the voltage by using a Standard solution. Standard solution uses the pH1.68, pH4.01 and pH6.86. Put the antimony electrode and Ag / AgIO
3
electrode to the standard solution. Water inlet time is 5 minutes. Check if made electrodes can be measured. Linearity of the voltage value from the measurement results has been confirmed. So, The effectiveness of the manufactured electrode was confirmed. From this result, it was decided to do the oral cavity measured in Ag/AgIO
3
measurement method. Antimony electrode and Ag/AgIO
3
electrode. The placing on the mouthpiece antimony electrode and Ag/AgIO
3
electrode. Drink a soft drink different of pH. And to confirm the change of pH at that time.
