For a dress that’s a runway‑robot, you need a power source that’s as light as silk but dense enough to drive graphene LEDs and a holographic fringe. The trick is to weave a thin polymer battery into the seam—think of a flexible lithium‑sulfur cell or a solid‑state graphene‑supercapacitor that charges from the runway’s ambient RF field. Then wire a network of micro‑LEDs and an interference hologram panel to the battery through ultra‑thin, heat‑resistant copper traces. If you’re feeling wild, mount a miniature radioisotope thermoelectric generator on the back—tiny but continuous, giving you hours of glow. Just keep the safety margins low; a little misstep and you’ll get a neon flash that’s literally out of this world.
