目的：本研究的目的是开发一种传感器片测量舌头的压力在吞咽过程中，并澄清其有用性，通过比较它与传统的压力传感器安装在腭plate.Methods：触觉传感器系统被用于测量系统的建设。在此基础上，根据对60个上颌骨铸型的形态学分析，设计了一种厚度为0.1mm、5个测量点（3个点在正中线上，2个点在后外侧）、3种尺寸的T形传感器片，用于硬腭的测量。为了阐明传感器片的感测特性，将传感器片的输出水平与相同负载下的传统压力传感器的输出水平进行比较。结果：舌压传感器的输出值小于压力传感器的输出值，舌压传感器的输出值小于压力传感器的输出值，舌压传感器的输出值小于压力传感器的输出值。两种传感器的输出水平高度相关（R = 0.952，P < 0.001）。虽然MP在每个传感器片的感测点也小于压力传感器记录，MP收集的回归方程在我们的实验中得到的是非常相似的压力sensors.Conclusions：该系统可以用于评估舌活动口咽吞咽。(C)2009年日本口腔修复学会。由Elsevier爱尔兰出版。All rights reserved.
Purpose: The aim of this study was to develop a sensor sheet for measuring tongue pressure during swallowing and to clarify its usefulness by comparing it with a conventional pressure sensor installed in the palatal plate.Methods: A tactile sensor system was used for the construction of the measuring system. Based on our preceding study, a T-shaped sensor sheet with 0.1 mm thickness, five measuring points (three points on the median line, two points on the posterior-lateral part) and three sizes based on the morphological analysis of 60 maxillary casts was designed for application on the hard palate. To elucidate the sensing characteristics of the sensor sheet, the output level of the sensor sheet was compared with that of a conventional pressure sensor under the same load. The maximal magnitude of tongue pressure (MP) during the swallowing of 15 ml water was recorded by a sensor sheet attached to the palatal mucosa and was compared with that recorded by pressure sensors installed in the palatal plate.Results: The output level of the sensor sheet was smaller than that of the pressure sensor. There was a high correlation between the output levels of the two sensors (R = 0.952, P < 0.001). Although MP at each sensing point of the sensor sheet was also smaller than that recorded by the pressure sensors, MP collected by the regression equation obtained in our experiment was quite similar to that for the pressure sensors.Conclusions: This system could be useful for evaluating tongue activity during oropharyngeal swallowing.
