Graphene-enhanced triboelectric footpath electricity generator for large-scale output planks suspended by rare-earth metal magnets

The invention is comprised of individual planks with positively charged triboelectric pads attached, connected by copper strips and suspended by neodymuim magnets over a mirrored overlaying of planks, of the same length and width of the prior, with negatively charged triboelectric pads also connected by a copper strip. The overlayed planks stabilized by wood pegs.

BACKGROUND

Triboelectric generators (electricity from oppositely charged surface interaction and where energy output is surface area dependent) are currently an emerging technology primarily used on a small-scale for the charging of electronics i.e. watches and phones by kinetic energy from human movement for example a watch charger that produces 132 mW per at 8.4 square centimeters as shown in U.S. pat app Ser. No. 2014/0084784 A1. By extrapolating triboelectric material surface area to a larger scale, as shown in Gomes et al, arVix:1803.10070[comd-mat.mes-hall] (2018), would allow powering of larger devices, as illustrated herein but not limited to the collective surface area of 6,830 square centimeters. By connecting individual triboelectric units with copper, enhancing triboelectrically active material backing with graphene where the use of graphene which is 13 times more conductive than copper as shown in Sharma, K. R. Graphene materials. N.Y. 2014.pp 9, to conduct a larger amount of electricity from the triboelectric material of the embodiment to the copper strips, where the copper strips connect the individual units and allow for connection to further consecutive units of the embodiment and subsequently to an energy storage unit.

BRIEF SUMMARY OF INVENTION

The objective of this invention is to provide a workable, stable, and greater source of electricity for the charging of larger devices by graphene enhancement, increased surface area of triboelectric materials, and use of long-lasting frame and suspension materials i.e. rare-earth metal magnets and planks. Further objectives, novelty, and advantages of the invention will be elucidated within the following description.

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIG.1,FIG.1shows the front view of the embodiment where21depicts two wood rods for stabilizing the opposing planks26and29. Opposing neodymium magnets22with same pole facing each other for suspension and allowance of compression from foot-traffic and allowing the top planks26to return to their initial position due to magnetic repulsion. Opposed charge triboelectric strips pads23and24are exactly aligned and reinforced by the planks for evenly distributed surface interaction for optimal electricity production.

Referring toFIG.2,FIG.2illustrates the assembled portion of the embodiment where25depicts a strip of copper to distribute the electricity created from compression opposed surface interaction produced by foot-traffic connecting the individual triboelectric pads23which have the dimensions of 84 centimeters by 7.62 centimeters or 638.7 square centimeters as embodied, attached by adhesive to the planks26with dimensions 121.92 centimeters by 10.16 centimeters or 1,238.71 square centimeters. The Neodymium magnets22, adhered by adhesive to the inside of the planks, for suspension of the planks. Further,27depicts holes on side of the planks26to accept the wood pegs21that stabilize and connect the planks26.

RegardingFIG.3,FIG.3represent the opposing and mirrored assembled portion of the embodiment. Holes28in the planks29are to accept the wooden pegs21to connect and stabilize the planks29. The neodymium magnets22, adhered by adhesive to the inside of the planks29, for suspension of the planks. The planks29have the dimensions of 121.92 centimeters by 10.16 centimeters or 1,238.71 square centimeters where the opposing triboelectric pads24are attached by adhesive with the dimensions 84 centimeters by 7.62 centimeters or 638.7 square centimeters which are connected by a copper strip30for completing the circuit as shown inFIG.3.

Referring toFIG.4.31depicts the positive triboelectric pads material which is adhered to adhesive graphene covered tape32to conduct the electricity produced from compression of by foot-traffic to the copper strip2533depicts an extender, which is adhered to both32ofFIG.4and the plank26, that raises the triboelectric pad31slightly above the neodymium magnets22.
