A device for concealing a seam between a first and second surface includes a seam concealment body having a body surface, the body overlaying and attached to a first surface and a second surface, the body surface being substantially co-planar with a portion of the first and second surfaces, the seam concealment body configured to transition between a first shape and a second shape, wherein the transition permits movement of one or both of the first surface and the second surface such that the seam concealment body forms a hinge. The device also includes an active material in operative communication with the seam concealment body, wherein the active material is configured to undergo a change in at least one property upon receipt of an activation signal, wherein the change in at least one property is effective to transition the seam body from the first shape to the second shape.

1. A device for concealing a seam between a first surface and a second surface, the device comprising: a seam concealment body having a body surface, the seam concealment body overlaying and attached to a first surface and a second surface, the body surface being substantially co-planar with a portion of the first surface and a portion of the second surface, the seam concealment body configured to transition between a first shape and a second shape, wherein the transition between the first and the second shape permits movement of a selected one or both of the first surface and the second surface such that the seam concealment body forms a hinge; andan active material in operative communication with the seam concealment body, wherein the active material is configured to undergo a change in at least one property upon receipt of an activation signal, wherein the change in at least one property is effective to transition the seam body from the first shape to the second shape. 2. The device of claim 1, wherein the active material is disposed within the seam concealment body. 3. The device of claim 1, wherein the active material comprises a shape memory alloy, a ferromagnetic shape memory alloy, a shape memory polymer, an magnetorheological elastomer, a piezoceramic, or combinations comprising at least one of the foregoing active materials. 4. The device of claim 1, wherein the change in the at least one property comprises a change in a shape, a dimension, a phase, a shape orientation, a stiffness, or combinations comprising at least one of the foregoing properties. 5. The device of claim 1, wherein the active material is a shape memory alloy and the change in at least one property is a stress-induced superelasticity effective to allow reversal of the transition of the first shape to the second shape of the seam concealment body. 6. The device of claim 1, wherein the activation signal comprises a thermal activation signal, an electric activation signal, a magnetic activation signal, a chemical activation signal, a mechanical load, or a combination comprising at least one of the foregoing activation signals. 7. The device of claim 1, wherein one of the first surface and the second surface comprises an interior or an exterior surface of a vehicle. 8. The device of claim 1, wherein the respective one of the first or the second surface comprises a door panel, trunk lid, hood, window, tailgate, sunroof, moon roof, center console, storage compartment, or glove box.
