A highly efficient P-SSHI-based rectifier for piezoelectric energy harvesting is presented in this paper. The proposed rectifier utilizes the voltages at the two ends of the piezoelectric device (PD) to detect the polarity change of the current produced by the PD. The inversion process of the voltage across the PD is automatically controlled by diodes along the oscillating network. In contrast to prior works, the proposed rectifier exhibits several advantages in terms of efficiency, circuit simplicity, compatibility with commercially available PDs, and standalone operation. Experimental results show that the proposed rectifier can provide a 5.8x boost in harvested energy compared to the conventional full-wave bridge rectifier.
