Abstract:

In this study, a high quality Na0.52K0.435Li0.045Nb0.905Ta0.05Sb0.045O3 (LS45-H) ceramic has been prepared from mechanochemically activated LS45 powder and normal sintering in air, which is promising for use in lead-free piezoelectric energy harvester. Herein, the LS45-H ceramic not only has less defect structure, but also has a more uniform and denser microstructure. Furthermore, the LS45-H ceramic exhibits excellent energy harvesting performance in the mode of cantilever-type structure, and a high output power of 11.5 mu W and output voltage of 5 V were obtained at the acceleration of 10 m/s(2). This work provides a simple method for preparing dense, uniform KNN ceramics without abnormal grain growth, and we believed that the LS45-H ceramic has a potential application in piezoelectric energy harvester for self-powered sources of wireless sensor network systems.
