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. |
