PZT is a traditionally preferred piezoelectric material due to its higher electromechanical coupling coefficient than other conventional piezoelectric materials. In order to reach low frequencies, it is crucial to increase the PZT
flexibility.


Recently, an efficient process to obtain flexible PZT thin films has been described. However, this process uses expensive sapphire substrates and requires a laser.

This technology offer presents an easy and cost effective chemical process which provides a flexible and efficient piezoelectric PZT thin film (Cf. pictures on the left).

KEY BENEFITS:

• Easy and cost effective process
• Chemical process
• Ability to work at low frequencies (between 0,1 HZ and 10 Hz)
