许多上肢缺陷患者渴望使用肌电假手，但由于某些原因，它们仍然没有被使用。其中一个最重要的原因是它的外观，这是由于人类的手和机器人的链接之间的结构差异造成的不适。这种结构必须以人体解剖为基础，才能创造出看起来更自然的假体。本研究以人体肌肉骨骼系统为基础，设计了一种具有骨骼、韧带、肌腱和多种肌肉的仿生假手。我们使用粘弹性角度传感器验证了提出的假手，以确定它是否像人类的手一样工作。我们还比较了假手和人类手指的指力。它可以像人类一样，通过多个伸屈肌肉来控制关节的角度和僵硬。
Many patients with upper limb defects desire myoelectric prosthetic hands, but they are still not used for some reasons. One of the most significant reasons is its external appearance, which has the discomfort caused by the structural difference between a human hand and a robotic link. The structure must be based on human anatomy to create a more natural-looking prosthesis. This study designed a biomimetic prosthetic hand with bones, ligaments, tendons, and multiple muscles based on the human musculoskeletal system. We verified the proposed prosthetic hand using the viscoelastic angle sensor to determine whether it works like a human hand. We also compared the finger force of the prosthetic hand with that of a human finger. It could be capable of controlling the angle and the stiffness of the joint by multiple extensor and flexor muscles, like humans.
