▎ 摘　　要

NOVELTY - The system has graphene pusher or bender that is provided for pushing and releasing a portion of graphene sheet into a groove. Graphene sheet (10) is provided to recover to be flat portion after removing the graphene pusher or bender from the groove, so as to reproduce electricity. Graphene sheet is comprised of graphene layers (12) and polyvinylidene fluoride (PVDF) layers (14) which are stacked alternatively. Polydimethylsiloxane (PDMS) insulating layers (18) are provided for insulating graphene layers, and both sides of stacked graphene layers are connected in parallel. USE - Graphene power-mill system. ADVANTAGE - The graphene power-mill system can be manufactured easily. The graphene power-mill system is easy to install and maintain. The graphene power-mill system efficiently harvests the wasted energy. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the graphene sheet.
