A mechanical sensor with graphene porous network (GPN) combined polydimethylsiloxane (PDMS) is demonstrated by the first time. Using nickel foam as template and chemically etching method, GPN can be created in PDMS-nickel coated graphene, which achieve both pressure strain sensing properties. Because of pores GPN, composite exhibit wide range highest sensitivity among foam-based sensors, respectively. In addition, it shows potential applications monitoring or even recognize walking states, finger bending degree, wrist blood pressure.
