• Stretchable, degradable semiconductors

  13-11-2019 14:30 via Geochemistry News -- ScienceDaily
  To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers have developed stretchable, degradable semiconductors that could someday find applications in health and environmental monitoring.
