用多点片状传感器测量磨牙咀嚼引起的咀嚼压力。传感器系统可以直接显示咀嚼力和与不同对象的接触面积。对海带零食的咀嚼进行了分析，认为海带零食的咀嚼难度大，是一种咀嚼训练的好食物。峰值力、峰值接触面积、峰值压力、持续时间、循环时间和冲量在受试者之间差异较大，但不受海带断裂力的影响。实验结果表明，人类至少在最初几次咀嚼难以用牙齿切割的海带样品时没有改变咀嚼模式。第一次咀嚼时，咀嚼压力较低，持续时间和循环时间较后几次咀嚼长。这表明受试者害怕未知的样本纹理。个体咀嚼峰值力与接触面积无关，但与峰值压力高度相关。冲动值高的受试者，咀嚼工作量大，咀嚼力高，但持续时间不长。
Masticatory pressure caused by chewing with molars was measured using a multiple-point sheet sensor. The sensor system is useful to directly indicate masticatory force and contact area with various subjects. Mastication of kelp snack, which is difficult to cut in several chewing strokes and thus seems to be a good food for masticatory training, was analyzed. Peak force, contact area at peak, peak pressure, duration, cycle time and impulse were highly varied among subjects, but were not influenced by the breaking force of the kelp. The experimental results show that humans did not change their masticatory pattern at least during the first several chews of the kelp samples which are difficult to cut with teeth. In the first chew, masticatory pressure is lower and duration and cycle time are longer than the following several chews. This suggests that subjects are afraid of an unknown sample texture. Individual peak force in mastication was independent of the contact area, but highly correlated with the peak pressure. Subjects with a high impulse value, corresponding to a large amount of work in mastication, had a high masticatory force, but did not show long duration.
