- With new “inks” containing semiconductors, researchers have been able to print LEDs for the first time
- To make the LED, the Princeton researchers chose quantum dots—semiconducting nanoparticles that emit very bright light in response to electrical current
- The researchers printed the LEDs on a contact lens after scanning it to make the shape of the printed devices match the curvature of the lens surface.
