A Combined Softening and Hardening Mechanism for Low Frequency Human Motion Energy Harvesting Application
Figure 8
Time history comparison between the measured (solid black) and the reconstructed signals (dashed blue) ((a), (c), (e)) and the harmonic amplitude of the reconstructed signals ((b), (d), (f)). Signal at waist at 5 km/h ((a), (b)) and leg at 9 km/h ((c), (d)) in -axis and -axis signal at wrist at 9 km/h ((e), (f)).
