This paper presents a first concept of a new biomimetic transradial prosthetic arm design, called 'MataPro-1,' that features a 3D-printed hand bone structure that mimics the shape of human finger phalanges and palm bones, flexible elastic joints, artificial muscles, and silicone flesh that covers and protects the internal components, provides restoring force, enables better gripping capability, and appears cosmetically realistic. The artificial muscles that actuate MataPro-1 are shape memory alloy (SMA) wires, which ensure effective grip strength for many everyday objects, without causing any noise. In order to avoid the need to cool SMA wires in the small volume of the fingers, the SMA wires are not routed through the finger phalanges. The SMA wires are spooled in the forearm, cooled by a fan only during the finger restoration process, and are connected to steel wires that are routed through the finger phalanges. The finger restoring force provided by the flexible joints and si...

具有形状记忆合金肌线的仿生trans骨假肢的研制

本文介绍了一种新型仿生trans骨假肢手臂设计的概念，称为“ MataPro-1”，其特征在于采用3D打印的手骨结构，该结构模仿了人的指骨和掌骨，柔性弹性关节，人造肌肉，以及覆盖并保护内部组件，提供恢复力，实现更好的抓地力并看上去美观的有机硅果肉。致动MataPro-1的人造肌肉是形状记忆合金（SMA）线，可确保许多日常物品的有效握力，而不会引起任何噪音。为了避免在小体积的手指中冷却SMA线，SMA线不穿过手指指骨。SMA导线缠绕在前臂中，仅在手指恢复过程中通过风扇冷却，并连接到通过指骨布线的钢丝。柔性关节和手指提供的手指恢复力
