Fig. 3: Experimental results of the electrogoniometry systems with a benchtop setup.

Device calibration with extrapolation (left), responses to the expected full range of joint motions (center), and responses to cyclic loadings (right) in the electrogoniometry systems for capturing flexion/extension of the fingers (a) and wrists (b). c Responses of the electrogoniometer for wrist radial/ulnar motions, including device calibration with interpolation (left), response to the expected full range of motion (center), and response to cyclic loading (right). The shaded areas in blue in the left panels indicate the range of calibration data.
