The scalable synthesis of an irregular composite surface impregnated with high-performance piezoelectric 0.3Ba0.7Ca0.3TiO3–0.7BaSn0.12Ti0.88O3 nanoparticles (0.3BCT–0.7BST NPs) for enhancing the power density of hybrid nanogenerators (H-NGs) using a contact–separation structure is reported for the first time. The designed high-performance butterfly wing structure type multiunit system, consisting of four simple arc-shaped H-NGs, has dual functionality as a stand-alone power source for light-emitting diodes and charging Li coin cells and as a self-powered air pressure sensor. Manyfold increments of the open-circuit voltage (VOC(p–p) = 572 V) and short-circuit current (ISC(p–p) = 1.752 mA) were observed for H-NG with an irregular surface compared with a piezoelectric nanogenerator (P-NG) (VOC(p–p) = 53 V, ISC(p–p) = 2.366 μA). Compared with the power density of a flat surface based H-NG (333 W/m2), the power density of a single arc-shaped H-NG with an irregular surface was 4-fold higher at 1336 W/m2, and that with a micropillar surface was twice as high (632 W/m2). A high functional property of fillers along with polydimethylsiloxane matrix improves the surface charge density of the composite film. The surface charge density of the H-NG was greatly influenced by the distance between the active layers, micropores, thickness, relative permittivity, and applied force.
