Synthesis and Analysis of Lead Free Piezoelectric Material
The Other Research Programs
Project Year： 2017.04 -
Lead-free KNbO3 piezoelectric films were grown on LiTaO3 single crystal by hydrothermal method. SEM and XRD results showed reaction time and KOH concentration affect crystal growth and grain size. Two dimensional finite element method (2DFEM) simulation was carried out prior to experiment and electromechanical coupling coefficient (k31) and mechanical quality factor (Qm) for different film thickness were calculated from simulation data.

圧電発電デバイスの研究では、単に圧電定数が高ければ優れた高電力となるわけではなく、高い限界振動速度(小さな非線形機械定数)の実現が本質的に重要となる。本研究は、
50μm以上の膜厚を持つ圧電厚膜を導入し、共振デバイスとしての観点から厚膜の性能向上を行い、エネルギー変換論に立脚した最適設計指針を確立することで、革新的な圧電発電デバイスを目指す。すなわち、本研究は独自開発した圧電厚膜材料を単に導入するだけでなく、本質的な設計指針を確立することで、新しい環境圧電発電デバイスとしてのパラダイムシフトをもたらす。それによってこれまでない新機能を持つ圧電発電デバイスとして医療・環境ヘルスへの応用展開を目的とする。
