Piezoelectric nanogenerators (PNGs) based on piezoelectric composites are emerging as promising energy harvesters for scavenging mechanical energy and converting it into electrical energy. However, owing to the unresolved issues of uniformity and reproducibility with regard to flexible PNGs, composite-based PNGs do not fully satisfy the energy requirements of wearable electronics. Here, we rationally designed piezoelectric nanoparticles–polymer composites to overcome the practical limitations of existing PNGs. Our work represents the first approach to PNG fabrication via chemical reinforcement of composite systems. Benefiting from the unique composites, our composite system shows excellent dispersion of the PZT nanoparticles in the polymer matrices without the use of dispersing agents as well as high performance in voltage and current generation under applied flexural stresses. |
