Strain Calculation by Image Processing
Table: Calculated area strain versus actuation voltage at different pre-strained sample
The table below shows the strain value's of DE sample at various voltages. The '-' in the above table represents that the strain value is not calculated at that voltage. After dielectric breakdown of the film the DE sample no longer actuates.
The above table has been plotted in the figure below
