The objective of this study was to elucidate the dynamic mechanism of infant tongue movement during sucking. We developed an integrated device with sensors for three-dimensional force measurements applied by the tongue to an artificial nipple. Three mini-size built-in cantilever sensors were installed in each of three sides of the regular hexagonal prism (nine sensors in total) inside the artificial nipple. Signals from the force sensors were amplified and displayed on a PC monitor via USB in real time. We conducted measurements using the system and confirmed that signals were outputted from all nine sensors. The output waveforms and force distributions showed that the force applied was larger at the nipple tip than at the nipple root and moved from the nipple root to the nipple tip.
本研究的目的是阐明婴儿吮吸时舌头运动的动态机制。我们开发了一种集成设备，该设备带有传感器，用于测量舌头对人工乳头施加的三维力。在人工乳头内部正六棱柱的三个侧面各安装了三个微型内置悬臂传感器（总共九个传感器）。力传感器的信号通过USB实时放大并显示在电脑显示器上。我们使用该系统进行了测量，并确认所有九个传感器都输出了信号。输出波形和力分布表明，在乳头尖端施加的力比在乳头根部大，并且力从乳头根部向乳头尖端移动。
