Just like your body self-heals after you get a cut, scientists are in the midst of developing a new, innovative technology which enables fabric or devices that are printed with a special magnetic ink to “heal” themselves. The magnetic ink has tiny particles of magnet embedded within it that attract to one another when there is a lesion in the fabric. The latest technology allows cuts up to three millimeters long to be repaired in a mere fifty milliseconds. This new technology replaces the traditional “self-healing” mechanism used in materials and fabrics known as polymerization. This ink is certainly not limited to clothing, and scientists anticipate that it will have a wide diversity of uses in various different fields ranging from clothing to solar panels to medical devices. In addition, an important advantage of this new technology is that is it inexpensive, which will make it marketable and practical. This new application could save large amounts of time and money by allowing devices to continue to operate and be useable without the need for repair or a replacement device.
