Abstract
An energy harvesting system and method includes a rotatable member with an electrically conductive coil mounted to the rotatable member and adapted to move with the rotatable member such that the movement of the coil through a magnetic field induces a voltage in the coil. An energy storage device is coupled to the coil.
Claims16
An energy harvesting system, comprising:
- a rotatable member;
- an electrically conductive coil mounted to the rotatable member and adapted to move with the rotatable member such that the movement of the coil through a magnetic field induces a voltage in the coil, wherein the magnetic field is generated from a magnetic field source outside of the rotatable member;
- an energy storage device coupled to the coil and configured to receive and store energy from the coil;
- and
- an electronic device configured to receive energy from the coil and the energy storage device.
2 more elements
A method of producing an energy harvester, comprising:
- providing a tire,
- mounting a conductive coil inside the tire;
- connecting the coil to a sensor to power the sensor;
- and
- connecting the coil to an energy storage device inside the tire to store the energy generated in the coil.
2 more elements
A tire system, comprising:
- a tire;
- an electrically conductive coil mounted to the tire and adapted to move with the tire such that the movement of the coil through a magnetic field induces a voltage in the coil, wherein the coil defines an axis generally radial to an axis of rotation of the tire, and wherein the magnetic field is generated from a magnetic field source outside of the tire;
- an energy storage device coupled to the coil and configured to receive and store energy from the coil;
- and
- a sensor mounted to the tire, wherein the sensor is coupled to the coil to receive power from the coil and the energy storage device, wherein the received power energizes the sensor,
- wherein the coil has a predetermined number of turns based on the sensor to receive power.
