World's smallest home is so tiny even a mite won't fit through door

Scientists have taken the tiny house trend to a whole new level. Using a new nanorobotic system, French scientists built a'microhouse' on top of an optical fiber that's as thin as human hair, which is 75 microns thick. It measures just 20 micrometers across but has several stunningly accurate details, including a front door, windows and even a tiled roof. A team of French scientists from the Femto-ST Institute built a 20-micrometer wide'microhouse' (pictured) on top of an optical fiber to demonstrate a new nanorobotic system A team of French scientists from the Femto-ST Institute detailed the process of creating the microhouse in new study published Friday in the Journal of Vacuum Science & Technology A. The new nanorobotic system, called μRobotex, uses a combination of technologies, including a tiny maneuverable robot, a focused ion beam and a gas injection device. To construct the microhouse, the scientists used a mix of origami and nanometer-precise robotics.
