New technology incorporating electronics and functional inks is likely to be in our near future. Self-healing materials requiring a chemical reaction have been termed polymerization. Older experimental endeavors required an external factor such as heat and were limited to smaller tears which would take hours to complete the mending process. This new technique developed at a nano-engineering lab at the University of California in San Diego, involves a solution which includes ink made with magnetic particles. If a garment is torn the magnetic particles in the fabric are drawn to each other and close the gap in seconds.
