Low d33 piezoelectric coefficient
Problem Phenomenon
d33 piezoelectric coefficient <20pC/N
Cause Analysis
The b crystal phase content is insufficient and the polarization conditions are improper
Solution
Stretching ratio 4-5:1, temperature 80-90C, polarization field strength 80-100MV/m
Key Takeaway
Maximizing the b crystal phase is the key to piezoelectricity
