Flexible pyramidal BiFeO 3 –BaTiO 3 microcone arrays integrated with P(VDF-TrFE) for self-powered mechanical sensing and energy harvesting
Flexible piezoelectric composites hold great promise for self-powered sensors and wearable electronics, but their performance is often limited by the low piezoelectricity of polymers, uneven dispersion of inorganic fillers, and poor interfacial stress transfer. To overcome these challenges, we fabricated a vertical...
