Gordon Cheng with CellulARSkin (image) Technische Universitaet Muenchen Caption CellulARSkin provides a framework for a robust and self-organizing surface sensor network. In the Walk Again Project, CellulARSkin is being used in two ways. Integrated with the exoskeleton, for example on the bottoms of the feet, the artificial skin sends signals to tiny motors that vibrate against the patient's arms. Through training with this kind of indirect sensory feedback, a patient can learn to incorporate the robotic legs and feet into his or her own body schema. CellulARSkin is also being wrapped around parts of the patient's own body to help the medical team monitor for any signs of distress or discomfort. Credit A.
