J. Hielscher, T. Meiss, R. Werthschützky & J. Block
This paper introduces a novel sensor concept for measuring muscular activity assessing the change of the skin surface curvature. The contraction of the rectus femoris muscle is expected to provide information on the user’s intention to rise from a chair. This information will be used for the control of a motorized lower limb orthosis to improve the quality of life of people suffering from muscle weakness. Electromyography is widely used for measuring muscular activity, but...
