1. A device for concealing a seam between a first abutting surface of a first article and a second abutting surface of a second article, the device comprising: a seam concealment body overlaying and being partially recessed into a selected one or both of the first abutting surface and the second abutting surface, wherein the seam concealment body comprises an active material, wherein the active material is configured to transition between a first stiffness and a second stiffness upon receipt of an activation signal, wherein the transition permits movement of a selected one or both of the first abutting surface and the second abutting surface such that the seam concealment body deforms with the movement of the surface to maintain concealment of the seam. 2. The device of claim 1, wherein the active material transitions from the first stiffness to the second stiffness when stressed by attempted movement of a selected one or both the first abutting surface and the first article and the second abutting surface and the second article. 3. The device of claim 1, wherein the active material comprises a shape memory alloy, a ferromagnetic shape memory alloy, a shape memory polymer, a magnetorheological elastomer, a magnetorheological fluid, an electroactive polymer, a piezoelectric polymer, a piezoelectric ceramic, or combinations comprising at least one of the foregoing active materials. 4. 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. 5. The device of claim 1, further comprising an activation device configured to provide the activation signal to the active material. 6. The device of claim 1, wherein the seam concealment body is formed of the active material. 7. The device of claim 1, wherein the seam concealment body further comprises a second body disposed on the seam concealment body, and wherein the second body conceals the seam concealment body. 8. The device of claim 7, wherein a body surface of the second body is substantially coplanar with a first upper surface of the first body and a second upper surface of the second body. 9. The device of claim 1, wherein the first abutting surface of the first article comprises a door panel, trunk lid, hood, window, tailgate, sunroof, moon roof, center console, storage compartment, or glove box. 10. The device of claim 9, wherein the second abutting surface of the second article comprises a vehicle body panel, vehicle roof, or dashboard. 11. The device of claim 7, wherein the second body comprises an active material.
