Summary: A novel energy harvesting interface using piezoelectric transducers is proposed for high-voltage energy harvesting, with pre-biasing of the PZT increasing damping force for higher energy extraction. The approach invests energy into the PZT only when deformation is detected, and stored energy is used to pre-bias the PZT for enhanced extraction. This interface successfully harvests energy from excitations with open-circuit voltages up to 100V.

Summary: This article proposes a compact self-sensing synchronized switch interface for piezoelectric energy harvesting. The interface circuit uses a modified buck-boost topology and implements time-sharing control. It works in strong discontinuous conduction mode and extracts a small amount of charge from the piezoelectric transducer for sensing, while extracting charge at a higher intensity for energy harvesting. The self-sensing mechanism is studied theoretically and validated through experiments.

Summary: A new self-powered CMOS synchronous electric charge extraction circuit is proposed for pressure-type piezo-electric energy-harvesters. The circuit utilizes peak detectors with precharging and body-drive enhanced PMOS switches to reduce switching phase-lag and improve efficiency. The overall harvesting efficiency is 78.04% at a peak voltage of 3.5V, significantly higher than other self-powered CMOS energy extraction circuits. The circuit can extract charge from commercial-off-the-shelf pressure sensors, providing an additional feature for piezoelectric pressure sensors.

Summary: Nonlinearity has enabled energy harvesting to advance toward higher power output and broader bandwidth in monostable, bistable, and multistable systems. However, operating in the preferable high-energy orbit (HEO) rather than the low-energy orbit (LEO) for making such advancement has restricted their applications. This paper proposes a self-contained solution for time-sharing orbit jump and energy harvesting using a monostable nonlinear system and a switched-mode bidirectional energy conversion circuit. The proposed solution enhances the practical utility of nonlinear energy harvesting technologies toward engineering applications.

Summary: This article presents a multi-input piezoelectric energy harvester (PEH) that utilizes a multi-input series synchronized switch harvesting on inductor (MIS-SSHI) rectifier and noninterruptive maximum power point tracking (MPPT) technique. The proposed MPPT solution tracks the vibration states of multiple piezoelectric transducers (PZTs) to ensure maximum power output for the MIS-SSHI rectifier, without interrupting the energy harvesting process for open-circuit voltage detection. Experimental results validate the feasibility of the proposed MPPT solution, achieving a peak MPPT efficiency of up to 98% for multi-input rectifiers.
