Ferrofluidic, electromagnetic power generator

DETAILED DESCRIPTION The ferrofluidic, electromagnetic power generators constructed in accordance with the principles of the present invention consists of: a sealed, elongated housing made of non-magnetic material partially filled with ferrofluid; an electrical coil wound of insulated, electrically conductive wire disposed about a portion of said housing; a permanent magnet and two magnetic frames.
The permanent magnet, the magnetic frames and the magnetized ferrofluid form a magnetic circuit encompassed by said coil.
Said electromagnetic power generator may be firmly attached to the outer steel rim of a vehicular tire.
Rotation and horizontal velocity of said tire will cause propulsion of the magnetized ferrofluid within the sealed housing and therefore, induction in the electrical coil.
In view of the above it is the principal object of the present invention to provide an electromagnetic power generator to power a pressure sensor and radio transmitter for the purpose of monitoring air pressure within the tire while the vehicle is in motion.
A further object is to provide such a device which may be small in size reliable, with no movable solid mechanical components.
A still further object is to provide such a device, which is simple in design and easy to manufacture.
The above objects and advantages are attained with the present invention by providing two embodiments of a ferrofluidic, electromagnetic power generator.
