Patent number: 9164051Abstract: In some aspects, an electrically responsive device can include a composite structure having spatially modulated structural properties that includes a substrate material having a surface and defining a plane; an electrically responsive material layer formed over at least a portion of the surface of the substrate material; an electrode material over portions of the electrically responsive material; and a stiffening material disposed along the electrode material, where the stiffening material has a thickness that varies and has regions of increased thickness that correspond with the regions of the composite structure along which the electrode material is disposed. The spatially modulated structural properties can include the regions of the composite structure along which the electrode material is disposed having the increased material stiffness, exclusive of the electrode material, relative to regions of the composite structure that do not include the electrode material.Type: GrantFiled: September 16, 2013Date of Patent: October 20, 2015Assignee: BioScale, Inc.Inventors: Brett P.
