“Artificial muscles” as shock absorber
These “electroactive elastomers” work by changing their form when exposed to an electrical field. If that field should be an alternating current, the material changes rapidly back and forth between two forms – it vibrates. Using smart electronics that monitor the frequency of vibrations in the environment, these elastomers can be made to vibrate at a complimentary frequency, resulting in the two frequencies essentially canceling each other out.
