NOVELTY - This new utility model claims of one of piezoresistive pressure vacuum meter, wherein the graphene comprises sensing element, a flexible carrier and wire, and the sensing component comprises graphene hollow graphite pipe. The flexible carrier is covered the graphene sensor element, and using the hollow graphite pipe seal, the flexible carrier and the graphene sensing component closely connected, so that when the flexible carrier generation type, the graphene sensing component with the flexible carrier together. The lead and the graphene connected with sensing element, used for forming electric current monitoring circuit. This new utility model providing vacuum meter type variable capacity is strong, pressure sensitive coefficient height, weight and sensitivity and the remote pressure piezoresistive vacuum as compared with notable.
