Self-Healing Magnetic Ink Developed by Nano Chair Highlighted in New York Times

A team of engineers led by NanoEngineering Chair Dr. Joseph Wang has developed a magnetic ink that can be used to make self-healing batteries, electrochemical sensors and wearable, textile-based electrical circuits.

The key ingredient for the ink is microparticles oriented in a certain configuration by a magnetic field. Because of the way they’re oriented, particles on both sides of a tear are magnetically attracted to one another, causing a device printed with the ink to heal itself. The devices repair tears as wide as 3 millimeters—a record in the field of self-healing systems.

Researchers detail their findings in the Nov. 2 issue of Science Advances. The research was also the subject of an article in the Nov. 2 edition of the New York Times.
