Claim 0:
1. An electrical responsive graphene-PVDF material, applying to convert at least a non-electrical energy into electrical energy, the electrical responsive graphene-PVDF material includes a first electron conducting end and a second electron conducting end, and comprising:
a polymer carrier, including a PVDF polymer and has a plurality of micro-pores;
a plurality of conductive micro-bodies, including graphene powder, the conductive micro-bodies are embedded in the polymer carrier and on at least part of the surface of the micro-pores, and the conductive micro-bodies provide at least a first conductive path to the first electron conducting end and provide at least a second conductive path to the second electron conducting end, the electrical responsive graphene-PVDF material generates a charge changing after receiving a non-electrical energy input, and outputting a plurality of electrons via passes through at least one of the first conductive path and the second conductive path to at least one of the first electron conducting end and the second electron conducting end;
wherein, the weight percentage of the graphene powder of the conductive micro-bodies is not less than 60% relative to the PVDF polymer of the polymer carrier; and
a plurality of piezoelectric micro-bodies, wherein the weight percentage of the piezoelectric micro-bodies is not more than 50% relative to the graphene powder.
