To investigate the factors that influence tongue volume, morphological features and the volume of the tongue and mandible in Japanese males were measured with Computed tomography (CT) data. The subjects were 40 Japanese males (Age : 52.6±12.5 years, Body Mass Index : 25.4±3.4 kg/m2). With all subjects, the tongue and mandible volume ( mean±SD ) were 78,990±10,607.8 mm3 and 87,806±12,079.6 mm3, respectively. The mean of T/M ratio would be important to determine the position and range of motion of the tongue was 91%. After measurement tongue volume, two-way sinuous actuator using air pressure and nylon strings was applied to fabricate the artificial tongue. Arrangement and interference of the each actuate were also verified so that artificial tongue can perform appropriate the form and position change. The curvaceous and rhythmical movements like a real tongue can be done by the prototype model without interference. Alternatively, self-moving artificial tongue was developed to achieve the swallowing without any power sources.

为了探讨影响舌体积的因素，利用CT测量了日本男性舌体和下颌骨的形态特征和体积。受试者为40名日本男性，年龄52.6±12.5岁，体重指数25.4±3.4 kg/m2。所有受试者的舌体和下颌骨体积(平均值)分别为78,990±10,607.8 mm~3和87,806±12,079.6 mm~3。T/M比值的平均值对判断舌体的位置和活动范围有重要意义，舌体活动度为91%。在测量舌体体积后，利用气压和尼龙线的双向弯曲驱动器制作了人工舌体。对各执行机构的布置和干涉进行了验证，使人工舌头能够进行适当的形位变换。原型模型可以无干涉地完成像真实舌头一样的曲线型和有节奏的运动。另一种方法是研制自主移动的人工舌头，以实现无动力源的吞咽。
