According to a report published in the May 2018 issue of the Journal of Vacuum Science and Technology, what could be called World Smallest House was assembled on the facet of an optical fiber by origami and welded in the μRobotex nanofactory. The scientist behind the Project propose a new way to easily manufacture many kinds of optical functions for light trapping based on nanoantennas, nanophotonic crystal, axicon or lattice, 3D biosensor with origami, and nanopatterning surfaces or carbon nanotubes, etc.

According to a report by LiveScience Micro house has each wall spanning about 0.0006 inches in length (15 micrometers, or 15 millionths of a meter), the humble chalet is too small to accommodate a dust mite, an amoeba or a sperm cell. It’s about 10,000 times too small to host a tardigrade; it’s even too small to hold a piece of tardigrade poop.

So, why build a house so small that even a tardigrade can’t make use of it? Mainly just to prove it can be done. According to a new paper published in the May issue of the Journal of Vacuum Science and Technology, this project was a test of a new nanoconstruction platform known as the MicroRobotex (or μRobotex) station — a high-tech rig built at the Femto-ST Institute in Besançon, France, with the sole purpose of affixing microscopic, 3D components onto ridiculously small surfaces...........
