Researchers from the KTH Royal Institute of Technology have developed a new solid-state carbon fiber composite, whose shape can be modified using electronic impulses. Additionally, this new composite isn't affected by the issues most other composite face, such as weight and mechanical stiffness.
The composite has three layers, and two of them are carbon fiber. In the middle, there is a separator, with a mix of lithium-ions. The electric current enables the lithium-ions to move from a side to another, and bend the composite.
This new composite could be used in the making of wind turbine blades, maximizing their efficiency, or in airplane wings, that could move without hydraulic rudders or ailerons.
