In recent years, surface electromyography (sEMG) signals which are biomedical signals generated by muscles have been utilized to estimate human's muscular torque and predict their intention. In this paper, a variable stiffness exoskeleton which utilizes EMG signals to adjust the stiffness of the output link to meet different environmental requirements and guarantee the wearer's safety has been proposed...
Stroke patients may prefer to rehabilitate at home, which limits their access to appropriate training devices and safety without supervised assistance by qualified personnel. However, most training devices are bulky and lack adequate safety for home-based training. To address this limitation, we have developed a device with a variable stiffness actuator (VSA) that was designed in the vsaUT-II and...
