通过使用压敏片测量最大等长圆柱体抓握过程中的手指指骨力，为了增强手指压力，使用了球垫。图像分析系统已用于根据压敏胶片上污渍的密度来确定指骨施加的力。研究了不同圆柱尺寸的手指力的变化，并且还获得了指骨力中心的位置。本方法可用于分析指腹与物体的接触，也可用于优化手柄形状设计。
Finger-phalangeal forces during maximal isometric cylinder grasping have been measured by using pressure-sensitive sheets in order to intensify the finger pressure, ball mats have been used. An image-analysis system has been used to determine the force exerted by the finger phalanges from the density of stains on the pressure-sensitive film. The variation of the finger forces with different cylinder sizes has been investigated, and the locations of the phalangeal force centers have also been obtained. The present method is useful for the analysis of finger-pulp contact with an object, and also for optimizing handle-shape design.
