Dear Colleagues,
A Piezoelectric material is poled along z axis and the dipoles are aligned along Z axis.
The poled piezoelectric material under stretching and compressing along Z axis will not alter the direction of polarisation.
So, when periodic stretching and compressing is done, the dipoles will be aligned in the same direction. Only there is change in amount of polarisation due to stretching and compressing.
So the generated charge is less.
IS THERE ANY PROCESS OF CHANGING THE POLARITY DURING STRETCHING AND COMPRESSING ?
This is because, I think, the efficiency will be increased by this.
Please suggest.
Thanks and Regards
N Das
