Triboelectric Nanogenerators (TENG) suitable for mechanical energy harvesting typically have ultra-high open-circuit voltage in several hundreds of volts, challenging the energy extraction circuit (EEC) design required for charging load battery/capacitor. Here, we present a novel multi-shot switched EEC that extracts energy in multiple discrete steps to regulate the TENG voltage below the breakdown limit of the technology (70V in our case), making it suitable for Integrated Circuit (IC) implementation. The proposed strategy maintains high TENG voltage just below the breakdown limit to maintain higher electrostatic damping, and in-turn enhances the transduced electrical energy. Mathematical derivation of the circuit\'s output shows a constant transduction power at all load voltages eliminating any complex power-intensive Maximum Power Point (MPP) Tracking. The design and simulation of the proposed EEC in TSMC 0.18um BCD process achieve a maximum power conversion efficiency (PCE) of 54.5% and a 1.64x gain over the ideal conventional Full Wave Rectifier (FWR) circuit at its optimal MPP load.
