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/s(2),　Mn-doped　PZN-PZT　harvester　can　still　work　properly　without　damage,　and　the　output　power　density　is　as　high　as　162　x　10(3)　mu　W/mm(3).　This　research　shows　the　Mn-doped　nanoceramic　having　the　potential　application　for　building　multi-layer　micro-piezoelectric　energy　harvester.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
