Abstract
An energy harvesting device includes at least one first magnet configured to rotate along a first circular path in a first plane. The energy harvesting device includes at least one piezo-electric cantilever spaced apart from the first plane, the at least one piezo-electric cantilever being configured to bend in a direction substantially perpendicular to the first plane. The energy harvesting device also includes at least one second magnet coupled to the at least one cantilever and configured to overlap the at least one first magnet.
Claims20
An energy harvesting device, comprising:
- at least one first magnet configured to rotate along a first circular path in a first plane;
- at least one piezo-electric cantilever spaced apart from the first plane, the at least one piezo-electric cantilever being configured to bend in a direction substantially perpendicular to the first plane;
- and
- at least one second magnet coupled to the at least one cantilever and configured to overlap the at least one first magnet.
An energy harvesting device, comprising:
- a rotating plate configured to rotate around a rotational axis;
- at least one first magnet on the rotating plate;
- at least one first piezo-electric cantilever spaced apart from the rotating plate, the at least one cantilever being configured to bend in a direction substantially perpendicular to a rotation plane of the rotating plate;
- at least one second piezo-electric cantilever spaced apart from the rotating plate, the at least one cantilever being configured to bend in a direction substantially perpendicular to the rotation plane of the rotating plate and disposed opposite to the at least one first cantilever with respect to the rotating plate;
- at least one second magnet coupled to the at least one first cantilever and overlapping a circular path along which the at least one first magnet rotates when the rotating plate rotates;
- and
- at least one third magnet coupled to the at least one second cantilever and overlapping the circular path along which the at least one first magnet rotate when the rotating plate rotates.
An energy harvesting device, comprising:
- a plurality of supports;
- a plurality of piezo-electric cantilevers coupled to the supports;
- a plurality of rotating plates configured to rotate relative to the supports, the rotating plates and the supports being alternately arranged;
- a plurality of first magnets on the rotating plates;
- a plurality of second magnets on the cantilevers;
- and
- a power transmission unit configured to convert a load into a rotation of the rotating plates,
- wherein the cantilevers are configured to bend in a direction substantially perpendicular to a rotation plane of the rotating plates as a result of magnetic forces between the first magnets and the second magnets.
