What is piezoelectric material?

• Piezoelectric materials generate charge when squeezed or deformed and convert mechanical energy into electrical energy
• They are used in sensors, transducers, and actuators in various devices
• Examples include PVDF, PVDF-trFE, ceramics, and polymers

What is PVDF-trFE?

• Polyvinylidene Fluoride-Trifluoroethylene (20 mol% trFE)
• It exhibits enhanced piezoelectric properties compared to PVDF alone

What is d_33?

• Piezoelectric coefficient
• d_33=*Delta;Q/&Delta:F

What is PVDF-trFE Phase?

• Alpha phase is non-polar with a disordered molecular structure (as-printed material )
• Beta phase is polar, ordered, and demonstrates enhanced piezoelectric properties (poling is required)
