Perovskite ferroelectric materials present evidently anisotropic characteristics on piezoelectricity. Here we successfully controlled the morphology and orientations of BaTiO3 particles and obtained the highly oriented film by a facile interfacial self-assembled method. A high output flexible piezoelectric generator based on highly oriented BaTiO3 film was reported. The oriented BaTiO3 film based piezoelectric generator were used to harvest the energy of human body movement and the generator fixed on finger provided the highest open circuit output voltage of 0.53 V and short-circuit current of 70nA, respectively. ? 2013 IEEE.
