| Abstract | INTRODUCTION Limb loss plagues over a million individuals in the U.S. alone [1], and it is a disability that greatly affects quality of life. The increased availability of 3D printing has allowed for an influx of new prosthetic designs [2]. Although some previously published papers have reported designs based on muscle wires, most of these designs do not have a humanoid appearance [3], do not have flesh material to protect the internal components and provide restoring force [4], or do not have a locking mechanism to help save electric current to the wires [5]. This work proposes a new innovative prosthetic hand design that features a 3D-printed plastic bone structure that mimics the shape of human finger bones; flexible elastic joints; a silicone “flesh” cover that protects the internal components, provides restoring force, enables better gripping capability, and appears cosmetically realistic; and a non-invasive, intuitive control system. The prosthetic is actuated by shape memory alloy (SMA) muscle wires to allow multiple gripping positions, which can then be locked into place to conserve power and increase effective grip strength. Control of the prosthetic is achieved by voice recognition software or an EEG headset that monitors brainwaves and facial expressions. Extensive research, analysis and testing has been done to optimize the actuation and controllability of the design. |
