Background: This work has developed a novel piezo-tribo-electric nanogenerator (P-TENG) that is capable of converting mechanical energy into electrical energy when operating in compressive mode. Methods: An arch-shaped P-TENG device was formed using an optimal piezoelectric polymer composite, which was fabricated using a polydimethylsiloxane (PDMS) matrix that was modified with piezoelectric (Ba0.85Ca0.15) (Ti0.90Zr0.10)O3 (BCZT) ceramic particles and electrically conductive multi-walled carbon nanotubes (MCNTs). A high filler loading of BCZT (40, 50, 60 wt%) and 3 wt% of MCNTs was formed into a 0-3 connectivity composite. Results: The P-TENG device containing 50 wt% BCZT exhibited the highest electrical output (VOC - 39.7 V, ISC 1.9 mu A, and maximum power - 157.7 mu W), compared to the other composites, when subjected to an alternating compressive load of 500 N at a 1 Hz frequency. Conclusions: This research provides new composite formulations for elastomeric-based energy generators that are responsive to low frequency mechanical oscillations.
