This study aimed to determine the steady-state errors of oral-based temperature sensors, that are embedded in mouthguards, using a robust assessment process.
Four electronic boards with temperature sensors were encapsulated in mouthguards made from ethylene-vinyl acetate (EVA). The error and time to reach steady-state temperature were determined using a thermostatic water bath during three different conditions (34, 38.5 and 43 °C). Subsequently, a case study of one volunteer wearing the instrumented mouthguard is presented.
The water bath tests showed that a mean absolute error of 0.2 °C was reached after a maximum of 690 s across all test conditions. The case study yielded an absolute error was 0.2 °C after 1110 s.
These results show that an instrumented mouthguard with temperature sensing capabilities can yield a consistent steady-state error that is close to the clinical requirements across a range of temperatures. However, the time it takes to reach steady-state temperature needs to be considered for these systems to correctly interpret the outcomes.
本研究旨在通过一个稳健的评估过程，确定嵌入在护齿器中的口腔温度传感器的稳态误差。
将四块带有温度传感器的电子板封装在由乙烯-醋酸乙烯酯（EVA）制成的护齿器中。在三种不同条件（34、38.5和43°C）下，使用恒温水浴确定误差和达到稳态温度的时间。随后，展示了一名佩戴装有仪器的护齿器的志愿者的案例研究。
水浴测试表明，在所有测试条件下，最长690秒后平均绝对误差达到0.2°C。案例研究显示，1110秒后绝对误差为0.2°C。
这些结果表明，具有温度传感能力的装有仪器的护齿器在一系列温度下能够产生接近临床要求的一致稳态误差。然而，对于这些系统而言，为了正确解读结果，需要考虑达到稳态温度所需的时间。
