Medical ‘microrobots’ could one day treat bladder disease, other human illnesses

“A team of engineers at the University of Colorado Boulder has designed a new class of tiny, self-propelled robots that can zip through liquid at incredible speeds — and may one day even deliver prescription drugs to hard-to-reach places inside the human body.  . . . .    The team makes its microrobots out of materials called biocompatible polymers using a technology similar to 3D printing. The machines look a bit like small rockets and come complete with three tiny fins.  . . . . If you expose the machines to an acoustic field, like the kind used in ultrasound, the bubbles will begin to vibrate wildly, pushing water away and shooting the robots forward.”  MORE
