Synergy Unleashed: Piezo–Tribo Hybrid Harvester for Sustainable Power Generation Toward Augmented and Virtual Reality Applications

Abstract

Recently, piezo–tribo hybrid nanogenerators are developed using the synergistic effect. Exploration of multi‐crystalline piezoelectric materials adds the advantage of mechanically to electrically converting hybrid systems. On the way, the multi‐crystalline 0.3Ba0.7Ca0.3TiO3–0.7BaSn0.12Ti0.88O3 (BCST) materials are characterized by the structural, vibrational, and ferroelectric properties. The synergistic effect‐based polydimethylsiloxane/BCST hybrid composite film is prepared for multi‐energy harvesting. The triboelectric nanogenerator produces a maximum output voltage of 210 V. The hybrid device obtains the maximum output performance of 326 V. The harvested energy is used to charge commercial capacitors and power low‐power electronics. The signal processing and analysis unit is constructed for monitoring or functioning in real‐time finger movement. In the future, this kind of system can be coupled with augmented and virtual reality applications.
