Researchers from the University of Illinois at Urbana-Champaign have created capsules that hold conductive nanotubes and can sit on circuit boards. Mechanical stress that causes a crack in the circuit would also split open some capsules and release the nanotubes to help bridge the gap.
Technology Review reports that outside experts praised the concept, which appeared last week in the Journal of Materials Chemistry.
The concept of self-repairing electric circuits could especially help submarines or satellites in situations when manual repair becomes impractical. Even lithium-ion batteries could benefit and avoid failures that could occasionally lead to explosive fires.Technology Review]
