Functional prosthetics hands which have the ability to help amputees perform tasks in daily life have been developed over many years. These hands need a control system which is fed information from sensors mounted on a prosthetic hand and human-machine interface. A variety of sensors therefore been developed for the prosthetic hand to measure fingertip force, joint angle (position), object slip, texture and temperature. However, most of the strain/stress sensors are attached to the fingertip. In this paper, the potential positions for strain sensors on the side of the finger link of the prosthetic hand are investigated that, in the future, will allow for force control in a lateral or key grip. With modified links of a Southampton Hand, some promising positions for strain sensors have been determined. On some of the links, the strain sensor can be used as an indicator to show the angle of the finger during a curling operation.
功能性假肢手已经经过多年研发，能够帮助截肢者完成日常生活中的任务。这些手需要一个控制系统，该系统从安装在假肢手和人机界面上的传感器获取信息。因此，已经为假肢手开发了各种传感器，用于测量指尖力、关节角度（位置）、物体滑动、纹理和温度。然而，大多数应变/应力传感器都附着在指尖上。本文研究了假肢手指连杆侧面应变传感器的潜在位置，未来这些位置将实现横向或钥匙握法中的力控制。通过对南安普顿手的连杆进行改进，已经确定了一些应变传感器的理想位置。在一些连杆上，应变传感器可用作指示器，以显示手指在卷曲操作过程中的角度。
