The smallest house in the world is only observed with a microscope

French engineers at the Femto-ST Institute in Besançon have just completed the construction of the world's smallest house with a height of only 15 micrometers.

This tiny house fits on the surface of an optical fiber and its thickness is smaller than a human hair, 10 micrometers wide, 15 micrometers high (1 micrometer = 0.001 mm).

Engineers have used the unique uRobotex system to build this house. Its operating principle is based on the interaction of a number of microscopic robots capable of producing small structures. All operations of the robot are controlled by the computer system.

The construction of the house is done in a vacuum chamber. Scientists must use microscopes to observe the assembly process.

In the future, engineers want to fully automate the assembly process of this system and hope to create microscopic structures up to a hundred nanometers in size.
