Cell phones are fragile: One slip of the fingers and yours can be headed for a disastrous meeting with the sidewalk, leaving you headed to the store for a replacement. Once again, however, nanotechnology might be coming to our rescue.
Clemson University scientists led by Apparao Rao say they’ve created a new process to help make phones, car bumpers, or other often-broken items a little more resilient. The researchers built beds of tiny coiled carbon nanotubes that act as spring-like shock absorbers, protecting the object from a fall or collision.
