Energy Harvesting Applications from Poly(ε-caprolactone) Electrospun Membranes

Journal Article


Abstract


  • Piezoelectricity is associated with crystalline materials that

    have noncentrosymmetric crystal units. This work reports the electroactive

    properties of poly(ε-caprolactone) (PCL) membranes produced by

    electrospinning. The individual PCL fiber shows an apparent piezoelectric

    constant of 5 ± 2 pm·V−1 with a longitudinal piezoelectric voltage

    coefficient of 0.25 Vm·N1−. Further, the PCL flexible electronic skin device

    exhibited superior mechano-sensitivity of 0.098 V·kPa−1

    , had the ability to

    measure small forces (1 mN), presents a remarkable output voltage

    stability (>16 000 cycles), and could accurately monitor human gait. The

    overall electroactive properties create opportunities in the development of

    environmentally friendly and low-cost energy nanoharvesting and wearable

    devices for human gait applications.
