A Smartphone That Heals Itself
Researchers have developed a "repair-and-go" approach to fixing small-surface cracks on digital devices using nanoparticles.
Researchers from the University of Pittsburgh and the University of Massachusetts have proposed a “repair-and-go” approach for fixing cracks on digital devices such as cell phones. This interesting development in technology uses microcapsules filled with a solution of nanoparticles that repair damaged surfaces and could extend the lifetime of a device.
In a paper published last month in Nature Nanotechnology, the team described their approach, which was inspired by the ability of white blood cells in the body to heal wounds on-site. The “repair-and-go” technique involves a flexible nanoparticle-containing microcapsule rolling across a damaged surface. It stops to repair any defects it finds by releasing nanoparticles into them and then moves on to the next defect.
