Abstract
In an embodiment, an energy harvesting apparatus includes a housing, a blade, and a power generation unit, which may include a power generation motor and a piezoelectric power generator. In the energy harvesting apparatus according to an embodiment, electrical energy can be generated by rotation of a blade by a slipstream generated during travel of a mobility vehicle. Electrical energy can be additionally generated by pressure and impact generated during rotation of the blade. When the blade is rotated at high speed as the driving speed of the mobility vehicle increases, pressure and impact can be reduced, thereby preventing damage to the blade or a piezoelectric element and thus improving the durability thereof.
