Design of a myoelectric 3D-printed prosthesis for a child with upper limb congenital amputation

For an early intervention with children, a prosthetic hand that is affordable, light-weight, and easy to wear and use is vital. Commercial prosthetic hands for children are often too expensive, burdensome and difficult to use. In this research, we attempt to address these issues with a novel design for a prosthetic hand for children. The proposed prosthesis implements two important features: the use of sound biofeedback and a soft socket with in-liner electrodes. We hypothesize that these features will make the hand prosthesis easy to use, lightweight and affordable, improving the control performance and increasing the acceptance rate. Preliminary experiments showed that the proposed prosthesis can be successfully controlled by a congenital amputation.
