Patent ID: 8269401

Claim:
A graphene power-mill system comprising: a graphene sheet configured for producing electricity on one or both sides thereof; a graphene sheet holder configured for engaging and holding the graphene sheet on a first or second side, wherein the graphene sheet holder comprises an insulator, wherein the graphene sheet holder is attached to an object; and a graphene pusher or graphene bender configured for pushing, bending, and releasing a portion of the graphene sheet, further comprising a groove provided on the first side of the graphene sheet holder, wherein the graphene pusher or graphene bender is configured for pushing and releasing a portion of the graphene sheet into the groove, and wherein the graphene pusher or bender has a shape fitting the groove, wherein the graphene sheet recovers to be flat after removing the graphene pusher or bender from the groove, so as to reproduce electricity, wherein the graphene sheet comprises one or more graphene layers and one or more polyvinylidene fluoride (PVDF) layers stacked alternatingly, and one or more Polydimethylsiloxane (PDMS) insulating layers for insulating graphene layers, and wherein both sides of the stacked graphene layers are connected in parallel.
