ENERGY HARVESTER USING FERROFLUID

摘要

Disclosed is an energy harvester using ferro-fluid according to one embodiment of the present invention. More particularly, disclosed is an energy harvester using ferro-fluid capable of improving energy production efficiency by reducing friction using a lubricant. The energy harvester according to one embodiment of the present invention includes a housing which includes an inner space, a magnetic part which is located in the housing, a harvest part which is formed on the outer side of the housing and generates power by the change of the magnetic force of the magnetic part, and a lubrication part which reduces the friction between the magnetic part and the housing. The harvest part can generate power by the movement of the magnetic part by an external vibration. The lubrication part includes the ferro-fluid. The ferro-fluid improves the efficiency of the energy generation by reducing a frictional coefficient between the housing and the magnetic part.
