Active material based seam concealment device

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;
• and
• 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.
