Leds

Although we're hearing a lot about stretchable electronics, the fabrication of their components is far beyond most people's abilities. Now, however, scientists have created inks that let anyone draw stretchable LEDS using regular ballpoint pens.

If diabetes progresses too far, it can result in a potentially blinding condition known as retinopathy. And while existing treatments are invasive and often painful, there may be new hope in the form of an LED-equipped contact lens.

As compared to their incandescent counterparts, LED bulbs are already known for producing a lot of light using relatively little electricity. According to a new study, however, a thin layer of nanoparticles could allow them to perform even better.
