Purdue University researchers have created microtweezers for the manufacture of tiny structures in micro electro mechanical systems (MEMS), printing coatings on advanced sensors, and live stem cell sphere manipulation.
The variety of miniature structures in MEMS could be expanded using this microtweezer manufacturing technology, which assembles components like microscopic Lego pieces moved individually into place, said Cagri Savran, an associate professor of mechanical engineering at Purdue University. The microtweezers are compact and user-friendly, he added, and the team has demonstrated them by assembling 40um-diameter polystyrene spheres into three-dimensional shapes (at left below). It can also place tiny particles on the tip of a microcantilever (at right below).
