For evaluating the amount of electrical conduction, we used them in a closed electrical circuit to show its ability to complete the circuit to light up a light emitting diode. In order to proof the capability of this method, the polyaniline polyester threads were used to complete the circuit. Bending and twisting did not change the conductivity of the resulting product. Following formula was used to convert electrical resistivity (ρ) to conductivity (1/R) for the corresponding cloth (with thickness of σ).
