The world’s smallest house is built on a foundation that's 300 micrometers by 300 micrometers – about half the size of an average grain of sand!
It comes with all the expected features though: four walls, seven windows and a chimney.
It was crafted by nano-robotics researchers at Femto-ST Institute, in Besançon, France, and was made using a layer of silica set on the tip of an optical fibre. The house was built inside the scanning electron microscope's vacuum chamber – with a technique similar to the art of origami.
That fibre that was used is less than the width of a human hair, and in order create the house, researchers used a platform called uRobotex.
It is hoped that the team can use this technology in the future to insert such fibres into blood vessels.
The dwelling was recently revealed in a paper published in the Journal of Vacuum Science & Technology A.
The focused ion beam is used like scissors to cut or score the silica membrane ‘paper’ of the house. Once the walls fold into position, a lower power setting is selected on the ion gun, and the gas injection system sticks the edges of the structure into place. The low-power ion beam and gas injection then gently sputters a tiled pattern on the roof, a detail that emphasises the accuracy and flexibility of the system.The American Institute of Physics
