NOVELTY - The utility model claims a graphene acceleration sensor, comprising a shell,a graphite alkene film, a balance weight block and an electrode; the graphite film and the balance weight block are suspendedly set in the shell, the balance weight block is set on the graphene, said electrode is set at the outside of the shell, comprising the first electrode connected with the graphene film, the second electrode connected with upper shell and the third electrode connected with the lower shell. The utility model fully uses high sensitivity of graphene film,putting the balance weight block on the graphene film,through the capacitance between the electrode between the upper shell and graphite alkene film in detecting movement,the change of the the capacitance between the graphite alkene film and the lower shell, computing the acceleration,with simple structure, because of high sensitivity of the graphene ,it can measure very small acceleration.
