We present for the first time how a Bennet's doubler conditioning circuit can boost the electrical energy extracted from an electrostatic Kinetic Energy Harvester (e-KEH) based on triboelectricity, commonly called Tribo-Electric Nano-Generator (TENG). After 1000 charging cycles, the harvested power is increased by more than 2 orders of magnitude with the Bennet doubler compared to a half-wave diode bridge. The maximum energy extracted by a 3×3 cm2 device made of PFA and aluminum is no less than 4.6 μJ per tap through the Bennet's doubler circuit.
