What’s in the thimble is the culmination of a decade’s worth of research into microelectromechanical systems (MEMS) — the technology of very tiny computers. MEMS are also called “smart dust,” and Dutta’s dust is the smallest known to humankind. Dutta is part of the Michigan Micro Mote, or M3, project at the University of Michigan, and M3 is on the cusp of releasing the blueprints for the “motes,” as Dutta calls them. As soon as the motes get approved by the University’s licensing office — which will happen any day now, says Dutta — M3 will release the blueprints on their mbus.io website, so that nimble-fingered researchers, hackers and Maker Faire enthusiasts alike might begin to build them. After years of trial and error, smart dust, long predicted by members of the scientific community, is finally here.
