A group of Massachusetts Institute of Technology (MIT) researchers developed a new printing process that improves on traditional flexography—a technique that applies ultra-thin layers of polymeric and colloidal inks to nonporous substrates. Flexography is important for many industries, including electronics manufacturing, and is often used to print on unconventional surfaces like paper and polymer films. Film transistors, RFID tags and transparent electrodes are just some of the mass-produced devices that benefit from this high-throughput process.
