Abstract
A gasket for shielding a seam between two surfaces includes a resilient member, a first electrode, a second electrode and a conductive layer. The resilient member has a first side and an opposite second side. The first electrode is disposed on the first side of the resilient member. The second electrode is disposed on the second side of the resilient member. The conductive layer envelops at least a portion of the resilient member, the first electrode and the second electrode. The resilient member includes a material that is compressed when a first potential is applied between the first electrode and the second electrode and that is decompressed when a second potential, different from the first potential, is applied between the first electrode and the second electrode.
