Extracted |deff| for P(VDF-TrFE) NWs and TFs. Gray tint indicates a measurement on the same location 30 min later. The voltage was applied to the sample, hence the up- and down-poled orientations.

This is an estimated velocity since data were not captured during poling.
The measurements were taken 15 and 45 min after poling.
