Figure 1 (IMAGE) Tohoku University Caption An overview of the experimental setting. Electrical signals were sent to the muscles from the developed electrical stimulation device (right), and the joint torque generated was measured using a force sensor. Electrodes were inserted inside the exoskeleton to transmit electrical stimulation to the three muscles (Protractor, Retractor, and Levator) targeted for electrical stimulation Credit Dai Owaki Usage Restrictions Reporters may use freely these materials in news coverage with appropriate credit information.
