As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

Various other objects, advantages, and features of the invention will become more readily apparent to those skilled in the art from the following detailed description when read in conjunction with the accompanying drawings, in which like reference numerals designate like parts throughout the figures thereof.

In one aspect, an embodiment of the present disclosure provides a system for generation of electricity using pressure applied to a

10

surface. The system facilitates the low cost and efficient electricity production utilizing pressure applied to a surface.

In one aspect, an embodiment of the present disclosure provides a system for generation of electricity using pressure applied to a surface, system comprising:

- one or more tiles; and

- a piezoelectric transducer communicably coupled to the one or more tiles,

wherein the piezoelectric transducer is operable to convert the pressure applied to the one or more tiles into electric charge, for the generation of electricity.

With reference to the drawings specifically to FIG.1, illustrates a schematic illustration of a system for generation of electricity using pressure applied to a surface, in accordance with an embodiment of the present disclosure. As shown, the system 01 01 for generation of electricity using pressure applied to a surface. The system 01 comprises one or more tiles 02. In an example, the tiles 02 may be coupled to a surface, such as a floor of a building. In an example, such building may be a railway station, a historical monument, an office space, a footpath, a road and so forth. In such instance, the tiles 02 will experience application of pressure, for example, due to a person walking on the floor comprising the tiles or due to movement of a vehicle on a road comprising the tiles.

Further, the system 01 comprises a piezoelectric transducer 03 communicably coupled to the one or more tiles 02, wherein the

11

piezoelectric transducer 03 is operable to convert the pressure applied to the one or more tiles 02 into electric charge. For example, one or more person may walk on the floor comprising the one or more tiles 02. Subsequently, the one or more tiles 02 may be compressed on one area (such as an area associated with contact of foot of the person) and expanded on another area thereof. Further, in such instance, a negative electric charge may be produced on an area of the piezoelectric transducer 03 associated with the expanded area of one or more tiles 02, and a positive electric charge may be produced on an area of the piezoelectric transducer 03 associated with the compressed area of the one or more tiles 02.

Thereafter, the one or more person may walk away from the one or more tiles 02, thereby removing the applied pressure. In such instance, an electric equilibrium is established by flow of the negative electric charge from the expanded area of the one or more tiles towards the compressed area of the one or more tiles. Further, such flow of the negative electric charge may be associated with flow of current i.e. generation of electricity.

In an embodiment, the system further comprises a storage device for storing the generated electricity. For example, the electricity generated due to application of pressure of the one or more tiles may be stored in the storage device. In one embodiment, the system comprises a balance level mechanism for maintaining a balance level between one or more tiles. For example, the balance level mechanism may enable in maintaining balance between

12

various tiles arranged in a row (or a column) such that a pressure applied to one tile is distributed evenly across the row of tiles. In such instance, the electricity generated by the row of tiles subsequent to removal of pressure therefrom is sent to the storage device.

According to an embodiment, the system further comprises an inverter. It will be appreciated that the electricity generated from the piezoelectric transducer 03 may comprise a DC (direct current) voltage. In an example, the DC voltage generated from the piezoelectric electric transducer 03 may be utilized for providing electricity to one or more devices that use DC power for an operation thereof. However, it will be appreciated that a majority of devices may require conversion of the DC voltage into AC (alternating current) voltage. In such instance, the inverter is operable to convert the DC voltage into AC voltage.

In one embodiment, the storage device is at least one of a lead acid battery and/or a capacitor. In an example, the storage device is a lead acid battery that is coupled to the inverter. In such instance, charge stored in the lead acid battery may be used by the inverter for providing electricity for operation of one or more devices. In another example, the storage device is a capacitor. In such instance, the piezoelectric transducer 03 may produce a pulsating DC voltage. Further, the capacitor may be operable to perform smoothening of the pulsating DC voltage and additionally, store the electric charge associated therewith. However, it will be appreciated that the capacitor may be operable to only store the electric charge

13

for a limited period of time (such as a few minutes). In such instance, the capacitor is further coupled to a lead acid battery for storage of the electric charge for an extended period of time.

According to an embodiment, the system further comprises a controller for controlling flow of electricity from the piezoelectric transducer 03. In an example, the piezoelectric transducer 03 may be configured for unidirectional operation, such as the piezoelectric transducer 03 may not be operable to receive electricity from one or more devices. It will be appreciated that such flow of electricity from one or more devices to the piezoelectric transducer 03 may result in damage to the piezoelectric transducer 03. In such instance, the controller may be operable to prevent flow of electricity back to the piezoelectric transducer 03, further ensuring a safe and reliable operation and further, prevention of damage to the system. In an embodiment, the controller comprises at least one of a diode and/or a thyristor.

In one example, the generated electricity stored in the storage device is used in an emergency situation, such as an emergency associated with power outage. In another example, the generated electricity stored in the storage device is used to power devices such as street lights, traffic lights and/or to provide power for charging mobile phones, vehicles and so forth.

In second aspect, an embodiment of the present disclosure provides a method for generation of electricity using pressure applied to a surface. The method facilitates the low cost and

14

efficient electricity production utilizing pressure applied to a surface.

In second aspect, an embodiment of the present disclosure provides a method for generation of electricity using pressure applied to a surface, method comprising:

- applying pressure to one or more tiles; and

- generating electricity by converting the applied pressure into electric charge.

With reference to FIG. 2 illustrates a flow diagram of a method for generation of electricity using pressure applied to a surface, in accordance with an embodiment of the present disclosure. As shown FIG. 2, illustrated are steps of a method 04 for generation of electricity using pressure applied to a surface. At step 05, pressure is applied to one or more tiles. At step 06, electricity is generated by converting the applied pressure into electric charge.

The steps 05 to 06 are only illustrative and other alternatives can also be provided where one or more steps are added, one or more steps are removed, or one or more steps are provided in a different sequence without departing from the scope of the claims herein. In an example, the method further comprises storing the generated electricity.
