Investigation of strain measurement on paper-based strain sensor using carbon electrical conductive paint

Abstract

Electrical strain gauge has been used widely in many applications, such as experimental strength of materials and structural health monitoring because of their low cost and durability in making measurements. Recently, a few new sensors have been developed using the constantan alloy to enhance the sensor's response and sensitivity. However, researchers have noticed that electrical conductive paints alternate their electrical resistance when subjected tomechanical strain. This
