Abstract:
We report electrically driven creasing of polyelectrolye hydrogel surfaces with low switching voltages (2-4 V). Deep creases (up to 70% of the swelled film thickness) can be reversibly formed and eliminated on time-scales of a few seconds, with control of crease locations by micro-patterning of underlying electrodes.
