N2 - We propose a power management strategy that maximizes the power harvested from a triboelectric nanogenerator using a Parallel Synchronous Switched Harvesting on Inductor (P-SSHI)-based rectifier. By analyzing the charge transfer from the rectifier to the DC-DC converter, we observe increase in the extracted power by limiting the rectifier capacitor discharging. We design and implement a power management system based on the proposed switching technique. The technique is suitable for integration into a power management system of smart selfpowered sensors, such as those used in smart knee implants following total knee replacement (TKR) surgery. We demonstrate 37% increase in the harvested power at the TENG interface compared to the conventional switching in P-SSHI-based rectifier.
