So far, the available prostheses have been using either electromyography (EMG) or electroencephalography (EEG) signals for controlling the device. Though these prosthetic hands have significantly helped patients to regain their ability to do daily chores, there are also complaints and limitations. These limitations include lack of precision in performance, unreliable electrode connectivity, and high maintenance and equipment costs. FUM-Hand V has, therefore, adopted a brand new method for controlling the prosthesis through magnetic fields.

Beginning with cosmetic replicas, FUM-Hand V project has eventually turned into a pioneering model worldwide. We have applied, for the first time, magnetomyography (MMG) signals in order to control FUM-Hand V. More specifically, the implementation of three magnets in the forearm through surgery enables the generation of magnetic fields each time the patient’s muscles contract. Once the type of magnetic field is determined in this way, the prosthesis then moves accordingly. This novel method can become the solution to the limitations of previous methods by reducing cost and increasing precision. Furthermore, our team is currently focused on manufacturing a new version of FUM-Hand V with lighter material so as to further resemble a human hand. This project is expected to change the scene of bionic hand technology towards more practical, accurate and user-friendly prostheses.
