TL;DR: An energy extraction enhancement circuit (EEEC) using an f-PEH based on piezoelectric (PZT) material is reported to improve energy harvesting from irregular human movement of a joint or limb as mentioned in this paper.

TL;DR: A novel energy harvesting (EH) interface for a flexible thin-film piezoelectric generator (FPEG) is proposed for EH from irregular human motion and successfully harvests energy from irregular pulsed inputs with 562% improvement compared with a full-bridge rectifier.

TL;DR: The measurement results with a test chip fabricated in 350nm process show that the proposed harvester successfully harvests energy from the excitation with VOC of up to 60V, higher than VMAX of 30V, with up to $3.9\times$ improvement compared with a conventional full bridge rectifier (FBR).

TL;DR: A sub-nW fully integrated switched-capacitor energy harvester for implantable applications is presented, where harvested current is directly injected to each stage of recursive voltage booster, significantly enhancing harvesting efficiency.

TL;DR: In this paper, a new switched capacitor (SC) converter that is capable of handling a wide range of load currents and output voltages is presented for on-chip DVS implementation.
