Enhancing the dielectric property of 0.69PZT-0.31PZNN thick films by optimizing the poling condition
We investigated how the applied electric-field’s magnitude and the poling time affected, respectively, the dielectric property and the microstructure of piezoelectric lead zirconate titanate/lead zirconate nic...

Optimization of a 0.69PZT-0.31PZNN thick film by controlling slurry viscosity and tape-casting blade height
We investigated how the viscosities of piezoelectric lead zirconate titanate/lead zirconate nickel niobate (PZT-PZNN) slurry samples affect the laminated-film densities based on various conditions of degassing...

Establishment of the evaluation standard and the analysis technique for the tip mass method in piezoelectric energy - harvesting systems
Two models were developed a pre-stress model and a no-pre-stress model for considering the effects of a tip mass with and without pre-stress induced by gravity, respectively. Three tip masses-6, 18, and 30 g-w...
