PZT data for zero pre-stress(scroll over thumbnails to enlarge).

Download: MATLAB .mat

Dr. Stefan Seelecke and Dr. Alex York collected this data on a Model P-802.00 actuator made by Physik Instrumente. The actuator is not pre-stressed.

Notes:
The .mat file constains a Matlab struct where the fields correspond to time [s], electric field [MV/m], polarization [C/m2], and strain [%].
