Engineers turned a sheet of paper into a stand-alone electronic controller

T775 Setup Researchers have found a way to turn ordinary paper sheets into electronic control and information input devices that work without a permanent power source.   A team of engineers from Purdue University has developed a highly fluorinated molecule coating that repels water, oil and dust. This omniphobic material allows multiple layers of circuits […]

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 […]
