This paper firstly presents an integration of a reconfigurable piezoelectric energy harvester array (RPA) and a parallel synchronized switch harvesting on inductor (P-SSHI) rectifier. The proposed design realizes maximum power point tracking by adjusting the combination of RPA. Compared with the traditional interface systems based on monolithic piezoelectric energy harvester (PEH), this design can work in a wider input voltage range and eliminate the DC-DC converters to avoid extra-passive components and to reduce the switching loss. RPA can be configured in series to reduce the inherent capacitance of PEHs, so as to effectively improve the extraction efficiency of P-SSHI rectifier.
