摘要：

Novel hybrid nanogenerators (HNG) with multifunctional materials are gaining immense interest due to their high electrical output and broad applications in the electronic industry. Intrinsic hybridization of single electrode triboelectric (SE-TE) and piezoelectric (PE) nanogenerators (NGs), that is, double layered (DL)-HNG can eliminate the real-time electrical grounding issues of SE-TE-NG and produces high output (176.41 V, 168.1 mW m(-2)) due to synergistic TE-PE effects of Multifunctional Composite film (MFC). The flexible MFC films are made-up of Cu2O-doped 0.3Ba(0.7)Ca(0.3)TiO(3)-0.7BaSn(0.12)Ti(0.88)O(3) nanoparticles (Cu2O-BCST NPs), which exhibits morphotropic phase boundary along with the polydimethylsiloxane polymer. Further, DL-HNG scaled up to 4 x 4 matrix (using the 3D-printed mask) can work as a flexible self-powered trackpad (or touch) sensor to control the mouse pointer in computer or touch screen display devices.
