Pmma optical fiber costume

Pretty Smart Textiles exhibition  – WIRED interview, San Fransisco

The Clear LED dress fits the bill for a lighter, more feminine outfit. The dress, created by Evelyn Lebis, has three pieces: the bodice and tutu — both made of tulle — and a long, sleeveless, open blazer.

The bodice includes some embroidery with glow-in-the-dark yarns that light up when bright artificial light is shined on them.

The blazer is woven with stretch fibers and yarn made of PMMA (Poly methyl methacrylate, a clear plastic that’s often used as a replacement for glass). The PMMA yarn transmits LED light. LEDs are attached at about a 90 degree angle to the yarn so with the help of a battery, the entire dress can glow in the dark.
