Abstract
Nanocomposites based on graphene nanoplatelets (GNP) were developed using recycled cellulose ac-etate from cigarette filters as the polymer matrix. Electrical conductivity measurements showed signifi-cant improvement with increasing GNP content, peaking at the saturation of the electrical network. The electromechanical performance of the sensors demonstrated a gauge factor (GF) near 20 at 3 wt% GNP content in the 0-2% strain range due to the tunneling effect. The new matrix ensures sensor sustaina-bility and stability through cyclic testing.
