Abstract Sensor devices, such as pressure gauges and membrane keyboards, contain Ag paths built from colloidal serigraphy. One of the steps in the manufacture of such devices is the deposition of graphite carbon to form a protective barrier that prevents the corrosion of the metallic paths. Nonetheless, several shortcomings are associated with such an approach. Corrosion protection requires the use of specialized high-valued materials to prevent even higher maintenance costs later on. The present work will address the possibility to replace graphite carbon coatings by conductive polymers. In this sense, Poly(aniline)/EPDM blends w
