Development of the arm-suit using pressure sensor

本研究的目的是开发一种利用压力传感器阵列来测量游泳运动员手部和手臂周围压力分布的臂装。利用压力传感器测量的压力值估算了划水过程中手部所受的流体力，并观察了压力分布。手掌前缘侧压力高于背侧压力。这种压力差发生在运动方向改变的过渡阶段之后，并且作用在手部上的流体力同时增加。因此，在游泳运动过程中的压力分布依赖于运动方向（速度）的变化。

The purpose of this study was to develop an arm-suit using the pressure sensor-array to measure the pressure distribution around swimmer's hand and arm. We put 12 small pressure sensors on swimmer's hand worn by a latex glove. The fluid force acting on the hand during sculling motion was estimated from the pressure sensor value, and the pressure distributions were observed. Pressure of the palm at the leading edge side was higher than that of dorsal surface. This pressure differences occurred after the transition phase of the motion direction change and the fluid force acting on the hand increased simultaneously. As a result, the pressure distributions during the swimming motion relies on the motion direction(velocity) changes.
