Designing prosthetic hands for children is challenging due to the limited space for electronics and the need of reducing the cost to cater for the constant growth of their hand. In this paper, we proposed an anthropomorphic hand prosthesis for children, using monolithic design and 3D printing of soft/compliant materials. The use of monolithic soft robotic structure provides a lightweight and compact design required in paediatric hand prostheses. The use of 3D printing also allows fabrication of customised products manufactured at low volumes in a cost-effective way which is of interest in prosthetic hand for children. The proposed hand/arm design has a total weight of 230gr including battery and actuation and control systems and a size similar to the biological hand of 5-7 years old children. The hand can provide two grasp types: pinch/tripod and power (cylindrical and spherical) and controlled by using two surface electromyography electrodes. The capability of the proposed hand prosthesis is demonstrated through grasping objects with different shapes and sizes.
为儿童设计假肢手具有挑战性，这是因为电子设备的空间有限，且需要降低成本以适应他们手部的持续生长。在本文中，我们提出了一种用于儿童的拟人化手部假肢，采用整体式设计以及软质/柔顺材料的3D打印技术。整体式软机器人结构的使用提供了小儿手部假肢所需的轻量化和紧凑设计。3D打印技术的使用还允许以经济高效的方式制造小批量定制产品，这对于儿童假肢手来说很有意义。所提出的手部/手臂设计，包括电池以及驱动和控制系统在内，总重量为230克，尺寸与5至7岁儿童的生物手相似。该手可以提供两种抓握类型：捏/三脚架抓握和强力（圆柱形和球形）抓握，并通过使用两个表面肌电图电极进行控制。通过抓取不同形状和尺寸的物体，展示了所提出的手部假肢的能力。
