Study on the Influence of Ferroelectric Materials on the Output Performance of Triboelectric Nanogenerators

Triboelectric nanogenerators (TENGs) have demonstrated as an effective way to harvest mechanical energy to drive small electronics. The density of triboelectric charges generated on contact surfaces between two distinct materials is a critical factor for dictating the output power. Herein, we demonstrate the unusual ability of ferroelectric materials to enhance the output performance of the triboelectric nanogenerators (TENG) by taking advantage of the dipole moment in the documents. The output voltage ranged from 100 V to 215 V under a constant contact force of 40 N. This work not only provides a new method of enhancing output power of TENGs but also offers an insight into charge transfer in contact electrification by investigating dipole-moment-induced effects on the electrical output of TENGs.
