Benjamin J. Blaiszik, Sharlotte L. B. Kramer, Martha E. Grady, David A. McIlroy, Jeffrey S. Moore, Nancy R. Sottos and Scott R. White Self-Healing Circuits: Autonomic Restoration of Electrical Conductivity (Adv. Mater. 3/2012) Advanced Materials 24
Self-healing of an electrical circuit is demonstrated by Nancy R. Sottos, Scott R. White, and co-workers on page 398 with nearly full recovery of conductance less than one millisecond after damage. Cracks break a conductive pathway in a multilayer device, interrupting electron transport and simultaneously rupturing adjacent microcapsules containing gallium–indium liquid metal. The released liquid metal restores the conductive pathway.
