ENERGY HARVESTER USING MAGNETIC FORCE AND METHOD FOR HARVESTING ENERGY

摘要

PURPOSE: An energy harvester using a magnetic force and a method for harvesting energy are provided to easily change a magnetic field by using a magnetic field modulator. CONSTITUTION: A magnetic field modulator uses an external force. The magnetic field modulator changes a magnetic field (310). At least one vibrating body is separated from the magnetic field modulator. The vibrating body produces vibration energy by the change of the magnetic field (320). The vibration energy is changed into electric energy (330). [Reference numerals] (310) Step where a changing magnetic field is formed using external force; (320) Step where vibration energy is generated based on the changing magnetic field; (330) Step where the vibration energy is converted into electric energy; (AA) Start; (BB) End
