Abstract

Abstract : Actuation of Anion‐Exchange Membranes In article number 2200888, Nicco Ulbricht, Thomas Wallmersperger, Maurizio Porfiri, and colleagues present anion‐exchange membranes as contactless actuators in salt solution. An external, imposed electric field (white lines) pushes anions from the solution (green atoms) into the membrane, along with their hydration shells (red‐white water molecules). Water inflates the cathode side of the membrane, which then bends toward the anode.
