Abstract
In this study, we aim to examine the triggering force for an efficient snap-through solution of hand shaking vibrations of a piezoelectric bistable energy harvester. The proposed structure works at very low frequencies with nearly continuous periodic vibrations. The static characterizations are presented as well as the dynamic characterizations based on the phase diagrams of velocity vs displacement, voltage vs displacement, and voltage vs input acceleration. The mass attached to the bistable harvester plays an important role in determining the acceleration needed for the snap-through action, and the explanation for this role is complex because of mass dependence on frequency/amplitude vibration. Various hand shaking vibration tests are performed to demonstrate the advantage of the proposed structure in harvesting energy from hand shaking vibration. The minimum input acceleration for snap-through action was 11.59 m/s2 with peaks of 15.76 and 2 m/s2 in the frequency range of 1.3–2.7 Hz, when an attached mass of 14.6 g is used. The maximum generated power at a buckling state of 0.5 mm is 11.3 µW for the test structure at 26 g. The experimental results obtained in this study indicate that power output harvesting of slow hand shaking vibrations at 10 µW and a load resistance of 1 MΩ.Keywords
