Researchers from the UCLA have developed an artificial muscle that is self-healing and it generates enough energy to power up a portable device like an iPod or iPhone. Qibing Pei, one of the authors of the study, said that one day this technique could be used to create walking robots.

The artificial muscle was created from carbon nanotubes which were used instead of electrodes and as a result, the new muscle could expand itself by 200 percent when the electricity comes in and there is no way that the muscle will fail because the carbon nanotubes stop spreading when put under pressure. Can’t wait to power my devices with the help of my muscles.
