Supercon 2024: Rethinking Body Art With LEDs
- Body art is being reimagined with the use of light-emitting diodes (LEDs) by Katherine Connell at the 2024 Hackaday Supercon.
- She created Sprite Lights, which are safe, light-up temporary tattoos that incorporate art, flex PCBs, screen printed batteries, and body-safe adhesive tape.
- Inspired by the neon-soaked 80s era, Katherine wanted a non-invasive glow-in-the-dark solution for body art.
- Early attempts using latex had challenges with allergies and intricate hand-soldering, leading to further experimentation with 3D-printing thin films and transparent PLA.
- Experiments with transparent silicone films and gallium alloys were also conducted, with copper tape eventually enabling the creation of more flexible circuits.
- Zinergy's ultra-thin non-rechargeable batteries were crucial for powering the Sprite Lights, delivering 3V and 20 mAh in a flat round design.
- The final product involved combining flex PCBs, Zinergy batteries, and custom die-cut stickers to create an art layer, LED circuit layer, and battery layer under 1.5 mm thick.
- Katherine's persistence in learning new skills and leveraging online resources led to the successful development of Sprite Lights, with a focus now on mass production.
- Sprite Lights not only represent innovative body art but also showcase the engineering journey behind creating self-glowing stickers.
- Through dedication and self-teaching, Katherine exemplifies how continuous effort and skill-building can lead to remarkable technological advancements.
