The present disclosure provides an electrohydraulic device. The device includes a battery having a vessel containing a flowable electrolyte. The battery may be a flow cell battery, such as, for example, a redox flow cell battery. In a flow cell battery, the flowable electrolyte may a catholyte and/or an anolyte. An actuator is in fluidic communication with the vessel of the battery. The actuator is configured to be actuated using the flowable electrolyte. A cation exchange membrane may separate the vessel into an anolyte side and a catholyte side. The actuator may be in fluidic communication with either side (anolyte side or catholyte side) of the vessel.

The present disclosure may be embodied as a method for creating a restriction pattern from a mask material having a strain (&#x3b5;) an for mapping elastomeric membrane having a strain (&#x3b5;) into a target 3D shape. The method may include discretizing the target 3D shape into a plurality of radial segments, and a radial strain (&#x3b5;) is determined for each radial position (r) on each radial segment of the plurality of radial segments. A restriction pattern is determined, wherein the restriction pattern comprises a quantity of mask material for each position r to provide a composite strain (&#x3b5;, &#x3b5;). In some embodiments, the method further includes depositing a first membrane layer into a mold and placing mask material into the first membrane layer according to the determined restriction pattern. The first membrane layer is cured.
