Camouflage suit
From Tardis Wiki, the free Doctor Who reference
A camouflage suit was an electronic bodysuit which could render the wearer invisible to the eye and to motion sensors.
An alien once infiltrated Torchwood Three's Hub wearing atop-of-the-range Yu-Ca grade camouflage suit, which he acquired from J’rizon 12. This suit left a shimmer in the air where he stood. Although invisible to the human eye, the wearer could still be detected with Night-vision goggles. When Ianto Jones damaged the suit it short-circuited and its cloaking mechanisms were disabled, rendering it fully visible. (PROSE: Virus)
