Various types of technology are present across all industries, including rosthetics.
Prostheses are medical devices intended to replace lost limbs or parts of them. Individual designs of hand prostheses serve different purposes and offer varying service lifespans. Energy transfer within such devices can be achieved through mechanical systems, electrical components, pneumatics, or hydraulics. Hydraulic systems are increasingly applied in compact devices due to their ability to generate high forces with great precision. This thesis presents the design and manufacturing of a hydraulic hand prosthesis, developed on the basis of an existing myoelectric prosthesis. A prototype was built and tested for functionality. The results showed that the prosthesis achieved the required functionality, though some design shortcomings were identified. With the first prototype, we managed to reach a maximum pressure of 108 bar, which is slightly below expectations. For this reason, a plan was developed to address the identified shortcomings, along with proposals for further work and development.
