Magnetic spring used for suspension of automobile, has piezoelectric element that is mounted on permanent magnets and is mechanically operated by compression and releasing of suspension to generate electricity using kinetic energy

摘要

The magnetic spring comprises two permanent magnets that are repulsive from each other. A coil moves the permanent magnets such that the permanent magnets are repelled or tightened to generate the current. A piezoelectric element is mounted on the permanent magnets and is mechanically operated by compression and releasing of a suspension of a vehicle for enabling the electricity generation using the kinetic energy.
