Electrochemical deposition technique and pressure-contact method are used to synthesize a superconductor / conductive polymer system. Three-point and four point resistance measurement are taken to obtain the sample (Bi2Sr2Ca2Cu3O10) resistance and contact (Bi2Sr2Ca2Cu3O10 / polypyrrole interface) resistance. Transition temperature (onset) was observed at 88 K for the electrochemically prepared system 88 K for the pressure mounted system. The Bi2Sr2Ca2Cu3O10 / polypyrrole contact resistance increases as temperature is lowered. Near transition temperature (onset), there is a decrease in the resistance at that interface. This decreasing contact resistance behavior is attributed to the proximity effect.
