MOTION-CONTROLLED MECHANO-ACTIVE MATERIALS

摘要

This invention concerns motion-controlled, layered mechano-active materials comprising at least one first fiber-based layer and at least one second layer capable of releasing or inducing tension, whereby the extension of the material is anisotropically controllable by heat and/or moisture. The motion control may be exterted by moisture or heat, e.g. by an electrical current. Products of the invention may be used for packaging or display purposes.
