Researchers have created tiny functional, remote-powered, walking robots, developing a multistep nanofabrication technique that turns a 4-inch specialized silicon wafer into a million microscopic robots in just weeks. Each one of a robot’s four legs is just under 100-atoms-thick, but powered by laser light hitting the robots’ solar panels, they propel the tiny robots.
According to TechXplore news, Researchers have harnessed the latest nanofabrication techniques to create bug-shaped robots that are wirelessly powered, able to walk, able to survive harsh environments and tiny enough to be injected through an ordinary hypodermic needle.
“When I was a kid, I remember looking in a microscope and seeing all this crazy stuff going on. Now we’re building stuff that’s active at that size. We don’t just have to watch this world. You can actually play in it,” said Marc Miskin, who developed the nanofabrication techniques with his colleagues.
Miskin and research colleagues developed a multistep nanofabrication technique that turns a 4-inch specialized silicon wafer into a million microscopic robots in just weeks. Each 70 micron long (about the width of a very thin human hair), the robots’ bodies are formed from a superthin rectangular skeleton of glass topped with a thin layer of silicon into which the researchers etch its electronic control components and either two or four silicon solar cells—the rudimentary equivalent of a brain and organs.
