摘要

The typical methods for developing artificial hands require long development time. It also takes assistance from specialists to fine-tune the details such as size, appearance, and fitting. Moreover, most highly-functional electric-powered prostheses are expensive, keeping them beyond the affordability of a large number of users. Sometimes the patients themselves need rehabilitative training to acquire skills in using these devices and accepting their new realities. To address some of these issues, a passive parametric 3D-printed artificial hand design is proposed in this work. The parameters are obtained from some anthropometric measurements from the non-injured hand. The technologies for rapid fabrication of custom designs are improving, making them more popular and affordable. The artificial hand model has been designed with parametric modeling techniques. The fabricated passive hand can perform up to 31 grasps out of the 33 grasps that the human hand can perform.
