1. A flexible vibrotactile device, comprising:
a dielectric support material including at least one hole therethrough for securing the flexible vibrotactile device to a textile by threading at least one fiber through the at least one hole;
at least one flexible electroactive element coupled to the dielectric support material and comprising a first flexible electroactive element and a second flexible electroactive element;
a first conductive electrode material positioned adjacent to and in electrical contact with the first flexible electroactive element; and
a second conductive electrode material positioned adjacent to and in electrical contact with the second flexible electroactive element opposite the first flexible electroactive element, wherein the first conductive electrode material is configured to apply a first voltage across the first flexible electroactive element, and the second conductive electrode material is configured to apply a second voltage across the second flexible electroactive element, wherein the second voltage is 180-degree phase shifted from the first voltage to induce movement in the at least one flexible electroactive element.
