Abstract:
A multifunctional member with a first active member (30), which is adapted to contract if exposed to a temperature above a first transition temperature range. A second active member (40), which is adapted to contract if exposed to a temperature above a second transition temperature range. A core member (20), which is adaptive for deformation. The first and second active members (30, 40) are attached on opposite or different sides of the core member (20). A heat source operatively connected to the first and second active members (30, 40) to expose them to transition temperatures. The first active member (30) contracts while above the first transition temperature range causing the second active member (40) to expand, wherein the second active member (40) is below the second transition temperature range. The second active member (40) contracts while above the second transition temperature range causing the first active member (30) to expand, wherein the first active member (30) is below the first transition temperature range.
