Smart coating warns of implant failure and kills bacteria

An illustration of a "smart" coating with bacteria-killing nanopillars on one side and strain-mapping flexible electronic sensors on the other. The coating, inspired by the antibacterial wings of dragonflies and cicadas, provides early warning of implant failure while killing infection-causing bacteria.
