DESIGN, DEVELOPMENT AND NUMERICAL VALIDATION OF NEURAL-CONTROLLED HAND-PROSTHESIS

This article presents the mechatronic structure of a neural prosthesis developed within the NerveRepack project, emphasizing both its functional design and structural integrity. The prosthesis was designed to enable bidirectional communication with a neural interface equipped with motor and sensory electrodes. The mechanical components were modeled in SolidWorks 2024 and fabricated through 3D printing using PLA material. To evaluate functionality, simulated signals replicating motor neural activity from the median and ulnar nerves were applied. Alongside functional validation, structural analysis using numerical methods was conducted to assess the durability and load-bearing capacity of the prosthetic components. The results confirm that the NerveRepack prosthesis can be effectively interfaced with the peripheral nervous system of upper-limb amputees, ensuring both mechanical reliability and personalized motor function.
