Title: Flexible foil moveable by non-mechanical means
Inventor: BROER DIRK J
IPC: B81B3/00
Filed: 2005-01-26
Abstract: A foilmoveable by non-mechanical means, such as light or heat, comprises an alternating array of first and second foilsections each resiliently and non-mechanically moveable between a flattened state and a bent state. The direction in which the first foilsections bend, when moved from the flattened to the bent state, is opposite to the direction in which the second foil sections bend when moved from the flattened to the bent state. When, in the flattened state, non-mechanically stimulating the first and second foil sections in unison, the first and second foilsections bend in opposite directions causing the foilto wrinkle, which results in a movement which is substantially linear. Using a different or removing the non-mechanical stimulus, the foil sections can be made to unbend resulting in a flattening and expansion of the foilto its original shape.
