Just blink and levitate objects, just move your fingernails and open the door. Chemically metalized eyelashes, RFID nails and conductive makeup are some examples of Beauty Technology products, an emergent field in Wearable Computers. Beauty Technology embedded electromagnetic devices into non-invasive beauty products that could be attached to the human body for interacting with different surfaces like water, clothes, the own wearer’s body and other objects, just blinking or even without touching any of these surfaces.
