The recorded piezo-voltage of nanocomposite fibers. (a) BT content scaffolds; PCL/BT20, PCL/BT30, and PCL/BT40, (b) BT and PANI content scaffolds; PCL/PANI5/BT20, PCL/PANI5/BT30 and PCL/PANI5/BT40 (c) output voltage of PCL/BT versus PCL/PANI5/BT (20, 30, and 40 wt.% BT), comparison of piezo-voltage of containing PANI and non-containing PANI scaffolds. PANI NPs had a synergic effect on piezoelectricity and enhanced the output voltage of nanocomposites. Conductive PANI NPs assisted to decrease the internal resistance of ternary nanocomposite by introducing conductive paths.
