Researchers from the ARC Centre of Excellence in Exciton Science at UNSW Sydney have demonstrated that OLEDs, a type of semiconductor material commonly found in flat-screen televisions, smartphone screens and other digital displays, can be used to map magnetic fields using magnetic resonance.

Published in the prestigious journal Nature Communications, this technique is able to function at microchip scale and – unlike other common approaches – does not require input from a laser.
