Abstract
- Electrical Impedance Myography (EIM) based on the four-electrode method is a common method for assessing muscle state in the fields of sports and medical rehabilitation. The electrode configuration of EIM significantly affects the measurement results. However, commonly used configuration of electrodes (size, spacing, arrangement) of four-electrode EIM method is not suitable for the wearable field, because of its large total area and low sensitivity. In this paper we propose EIM technique for real-time monitoring of the degree of muscle fatigue and we optimize commonly used electrode configuration for application in wearable field. Changing electrode arrangement from in-line (model A) to placing two pairs of electrodes are arranged symmetrically along the z-axis (model B) results in more compact electrode configuration and higher potential sensitivity, and also provides new attempts for the development of wearable devices in the future. Equivalent circuit model B is established and in-vivo measurements of the electrical impedance of the biceps muscle are carried out. The experimental results show that the variation in muscle electrical impedance measured using the optimal configuration of model B is twice that measured using the optimal configuration of model A. The optimized electrode configuration of EIM based on this approach is model B.
