Katia Vega seems to work at the intersection of the functional and the fabulous. It would be easy to think that technology research involving make-up would be perhaps a little frivolous but the miniaturisaton required alone is enough to refute that idea fairly thoroughly. She has created chemically metalised eyelashes and conductive eyeliner that transform a blink into a command and also RFID false nails that have the potential to unlock doors, act as tickets, pay for items or even allow a DJ to use the surface of water to mix tracks. Seriously powerful make-up.
