Abstract
The present invention relates to an apparatus system and method for power harvesting on roads and highways using piezoelectric generator. The invention is to provide a system and a method for power harvesting comprising a plurality of piezoelectric devices embedded in a road and configured to produce electrical power when a vehicle traverses their locations. The system includes a power conditioning unit and electrical conductors connecting said piezoelectric to said power conditioning unit. Harvested energy may be used locally in proximity to the energy generation location, stored for later use or transferred to be used in remote location.
Claims19
An apparatus for power harvesting from a road on which vehicles pass comprising:
- a base plate;
- a top plate;
- at least one piezoelectric device having a plurality of piezoelectric rods embedded in a matrix placed between said top plate and bottom plate wherein said at least one piezoelectric device is capable of producing electrical power;
- an elastic member connecting said base plate and said top plate capable of exerting compression force on said at least one piezoelectric device;
- a power conditioning unit;
- and
- electrical conductors connecting said at least one piezoelectric device to said power conditioning unit.
A system for power harvesting from a road having a surface and at least one lane comprising:
- a plurality of piezoelectric apparatii capable of producing electrical power in response to compressive strain;
- a power conditioning unit;
- electrical conductors connecting said plurality of piezoelectric apparatii to said power conditioning units,
- wherein said plurality of piezoelectric apparatii are embedded below the surface in two rows along at least one lane where wheels of traveling vehicles are most probable to pass, and
- wherein at least one of said plurality of piezoelectric apparatii comprises:
- a base plate;
- a top plate;
- at least one piezoelectric device placed between said top plate and said bottom plate wherein said at least one piezoelectric device is capable of producing electrical power;
- and
- an elastic member connecting said base plate and said top plate and exerting compression force on said plurality of piezoelectric devices.
