Training and calibration is normally required for the users of Electromyographic (EMG) control systems, which can require a lot of time and expertise. It is necessary to reduce training and calibration so that EMG control can be deployed in real-world applications, with minimal hassle. Based on our previous work, this paper investigates a novel method of using an automatic circumference measuring device to determine forearm circumference, in order to estimate maximum voluntary contraction (MVC)

A new load cell based automatic measuring circumference device is demonstrated, and an experiment is performed which confirms the potential of using forearm circumference for estimating MVC. Experimental results confirm the feasibility of the concept, and the performance of the developed device.
