What's better than successfully creating an artificial muscle that heals itself? Having that muscle charge your iPhone or other gadgets!
Combining breakthroughs in self-healing materials and artificial arms, University of California, Los Angeles researchers created such muscles that can generate electricity. The research could be used to make walking robots and develop better prosthetics that juice your iPod. Part of the technology is already being used in Japan to charge batteries using ocean waves.
The researchers used flexible carbon nanotubes as electrodes instead of metal-based films that fail after repeated use. If an area of the carbon nanotube fails, the region around it seals itself by becoming non-conductive preventing the fault from spreading to other areas.
