Fig. 1From: Effects of human limb gestures on galvanic coupling intra-body communication for advanced healthcare systemExperiment setup to investigate the effects of limb gestures on galvanic coupling IBC channel. For upper extremity channels (A1A2 and A1A3), the frequency response at each joint angle is measured with empty-handed, gripping force and loading. For lower extremity channels (B1B2 and B1B3), it is measured with the change of knee joint anglesBack to article page
