摘要	Dielectric loss is one of the important parasitic features of piezoelectric materials; nevertheless, its role in practical piezoelectric energy harvesting (PEH) systems has received little attention in previous studies. Based on the integrated equivalent impedance network model, this paper investigates the susceptibility of harvested power in PEH systems under different dielectric leakage conditions when different harvesting interface circuit is adopted. It shows that dielectric loss always counteracts power generation in PEH systems. In particular, harvested power degrades from the ideal lossless case more significantly under large dielectric leakage, or when power boosting interface circuits, e.g., synchronized switch harvesting on inductor (SSHI), are adopted. These results provide useful insight for the selections of piezoelectric material and harvesting interface circuit towards holistic PEH designs.
