摘要

我们开发了一个圆形(直径15米x 3.8毫米厚)剪切力传感传感器，由两个圆形金属盘和两个平弹簧组成，用于测量行走时足底表面和鞋垫之间的剪切。剪切力使顶部圆盘向施加力的方向移动。这种运动迫使位于顶部圆盘上的楔子，相对于施加剪切力的变化，增加或减少从LED传输到光电二极管的光量。工作范围为0 ~ 22.3N剪切，可通过调整金属弹簧刚度和尺寸进行调整。将两个换能器圆盘组装并用硅胶粘合。将传感器放置在鞋垫中，可以在正常步态时测量人足下的剪切力。

Development of a miniature plantar shear force sensing transducer

We have developed a circular ( 1 5 m in diameter x 3.8mm thick) shear force sensing transducer consisting of two circular metal discs and two flat springs to measure the shear between the plantar surface and insole during ambulation. Shear force causes the top disc to move in the direction of the applied force. This movement forces a wedge, located on the top disc, to either increase or decrease the amount of light transmitted from an LED to a photodiode, rela&ive to a change in the applied shear force. The operatiug range was from 0 to 22.3N shear, and could be altered by adjusting the metal spring stiffness and dimensions. The two transducer discs were assembled and bonded with silicone adhesive. Placement of the sensor into an insole allowed measurement of shear forces under the human foot during normal gait.
