By now, many have heard of printable electronics. Conductive ink is already being applied in asset tagging and logistics applications through RFID, within circuit boards to replace wiring, acting as radio antennas for vehicles, and even to protect surfaces in cold environments. As advances continue in printable electronics, the electrical conductivity of the ink is evolving to serve new energy storage functions, opening up a whole new world of possibilities, not least for the built environment. Researchers from Drexel University and Trinity College in the Republic of Ireland, have collaborated to create an ink from a highly conductive type of two-dimensional material called MXene. Their findings, published in a recent edition of Nature, describe an ink that can be used to print flexible energy storage components, such as supercapacitors, in any size or shape, using an inkjet printer. “Conductive inks have been around for nearly a decade and they represent a multi-hundred million dollar market […]
