Microbots capable of sensing environs could explore intestines, pipelines

Science
July 23 (UPI) -- Engineers at MIT have designed tiny, new robots capable of sensing their surroundings. The microbots, roughly the size of a human egg cell, could be used to explore hard-to-reach passageways, like the human intestines or a gas pipeline. Scientists designed the tiny robots by coupling electric circuitry to colloids, a mixture feating insoluble particles so small they never settle in water or air. Colloid particles always remains dispersed. "We wanted to figure out methods to graft complete, intact electronic circuits onto colloidal particles," Michael Strano, a professor of chemical engineering, told MIT News. Researchers have previously tried to turn small particles or molecules into robots, but scientists have mostly focused their efforts on improving the mobility of mi...
