IONIC POLYMER METAL NANO-COMPOSITE SENSOR WITH VIA MINIMIZING CRACKS IN ELECTRODE

The present invention relates to a flexible porous ionic polymer metal nano-composite (IPMNC) sensor with cracked minimized of a metal electrode comprising a membrane, wherein said membrane comprises a polymer blend of Poly(vinylidene fluoride trifluoroethylene-) and Polyvinylpyrrolidone and a ionic polymer (poly(2-acrylamido-2 methyl-1-propane-sulfonic acid) (PAMPS)); wherein said ionic polymer is directly attached on said polymer blend; and wherein said metal electrode is made up of platinum nanoparticles which are penetrated on surfaces of said membrane. The ionic polymer metal nano-composite sensor of the present invention has sensing voltage 800 mV, sensing current density 2.5 mA/cm2, and bending strain 0.009 mm/s at 0.2 Hz.
