Engineers invented acoustically controlled microrobots

Engineers invented acoustically controlled microrobots Researchers have developed microscopic remote-controlled mechanical devices whose motors are powered  ultrasound. They can find many uses in medicine.. Using 3-D nanoprinting technology, engineers at the École Polytechnique de lausanne have created tiny, cage-sized soft capsules made entirely of biocompatible hydrogel. Their key elements are acoustic micromotors and mechanisms that […]
