Energy harvesting characteristic in piezoelectric nanoceramics with high mechanical property

In this work, PZN-PZT piezoelectric nanoceramics were fabricated by SPS of nanocrystalline powders. It was found that Mn-doped nanoceramic possessed not only high mechanical properties, but also high FOMoff. Under high acceleration of 70 m/s2, Mn-doped PZN-PZT harvester can still work properly without damage, and the output power density is as high as 162 × 10−3 μW/mm3. This research shows the Mn-doped nanoceramic having the potential application for building multi-layer micro-piezoelectric energy harvester.
