摘要

A method for affecting volume change of an electroactive polymer (EAP) material (23) in a device (50), the method comprising the steps of: providing (41) an electrolyte (13), a first electrode (14) and a second electrode (15), said electrodes being arranged to be in contact with said electrolyte, wherein at least said first electrode (14) comprises said EAP material (23); setting (43) at least one parameter having external influence on volume change of the EAP material (23) to a determined value; and operating (45) the device under influence of the determined parameter value. There is also disclosed a device arranged to execute the method, a system comprising a working electrode and a counter electrode wherein at least the working electrode comprises an EAP material, a method for providing an EAP object, a use of means for removal of EAP material from a grown EAP object, a method for providing an EAP layer on a substrate and a use of a non¬ aqueous polar solvent to confine an EAP layer to a substrate layer.
