Carbon‐Enhanced Piezoelectric Materials and Applications

Piezoelectric materials possess the property of converting mechanical stimuli into electrical energy. The electroactive phase of the piezoelectric effect can be enhanced by adding nanofillers. In this chapter, the exploration of inorganic piezoelectric materials as energy harvesters is briefly discussed. Then, the focus is steered to organic piezoelectric materials, for instance, poly(vinylidene fluoride) and its copolymer due to their environment-friendly factor. Since generated electrical signals by organic piezoelectric materials are relatively low, researchers have proposed various methods to improve the generated signals, including the addition of carbon nanotubes, graphene-based materials, quantum dots, and fabrication methods. As a result, the improved performance of piezoelectric materials demonstrated the potential to be used as sustainable energy harvesters and biomechanical sensors.
