触觉传感是新型假手开发的重要组成部分。许多建立触觉信息返回患者的传入通路的方法变得可用，包括触觉器和传入神经的直接刺激。触觉信息也可以由低级控制系统使用，该低级控制系统为患者执行简单的任务，例如建立稳定的抓握和保持保持物体所需的抓握力。本摘要报告了基于半导体应变计的小型指尖称重传感器的设计。由于该称重传感器非常小（直径仅为8.5 mm，高度为6.25 mm），因此很容易安装到拟人机电手的尖端。通过将力和力矩数据的时间序列与从更大的高精度商用称重传感器获得的参考数据进行比较，对该称重传感器进行测试。
Tactile sensing is an important part of the development of new prosthetic hands. A number of approaches to establishing an afferent pathway back to the patient for tactile information are becoming available including tactors and direct stimulation of the afferent nerves. Tactile information can also be used by low-level control systems that perform simple tasks for the patient such as establishing a stable grasp and maintaining the grasping forces needed to hold an object. This abstract reports on the design of a small fingertip load cell based on semi-conductor strain gauges. Since this load cell is so small (measuring only 8.5mm in diameter and 6.25 mm in height), it easily fits into the tip of an anthropomorphic mechatronic hand. This load cell is tested by comparing a time series of force and moment data with reference data acquired from a much larger high-precision commercial load cell.
