We tried to develop a new device to detect laryngeal movement noninvasively. We made small piezo pressure sensors (length, 1.5 mm, width, 7.0 mm), and five of these were lined up with 3.0-mm intervals and embedded in the middle of a palm-sized urethane resin sheet. This sheet was lightly attached to the ventral surface of the neck near the laryngeal prominence. The first and second peaks obtained from each sensor should correspond to the period when the larynx moves to the upper and lower positions during swallowing. The mean maximum rising velocities for men and women were about 0.08 and 0.11 m/s, respectively. Similarly, the mean maximum lowering velocities for men and women were about 0.09 and 0.11 m/s, respectively. The swallowing latencies for men and women were about 0.49 and 0.53 s, respectively. In conclusion, we succeeded in developing a new device, which will be useful in evaluating the swallowing function.
我们试图开发一种新设备，用于无创检测喉部运动。我们制作了小型压电压力传感器（长度1.5毫米，宽度7.0毫米），将其中五个以3.0毫米的间隔排列，并嵌入手掌大小的聚氨酯树脂片中间。该片轻轻附着在喉结附近颈部的腹侧表面。从每个传感器获得的第一和第二个峰值应对应于吞咽过程中喉部向上和向下移动的时间段。男性和女性的平均最大上升速度分别约为0.08米/秒和0.11米/秒。同样，男性和女性的平均最大下降速度分别约为0.09米/秒和0.11米/秒。男性和女性的吞咽潜伏期分别约为0.49秒和0.53秒。总之，我们成功开发了一种新设备，这将有助于评估吞咽功能。
