Re-Fill replicates finger movement by interpreting the body’s EMG signals. When patients visualize moving their missing fingers, it stimulates certain hand muscles they never realized they had before. Re-Fill interprets these muscle signals and replicates patients’ finger movements accordingly. Two pairs of four-bar linkage systems implement a movement path for proximal phalanx and middle phalanx, as well as realize two degree-of-freedom mechanisms from a single linear motor. And the more user used it, the more sophisticated user’s EMG data signals became. Furthermore, the prosthetic appendage allowed him to see how each finger related to the others, thereby enhancing finger movement even further. In most society, people have difficulty accepting others’ differences. As a result, patients with missing fingers hide their disability as best they can, so as not to seem abnormal to their peers. Re-Fill can help restore these socially disrupted individuals to their former social standing
