BuzzSkyline writes "The world's smallest robotic hand has been built by Yen-Wen Lu and Chang-Jin "CJ" Kim at UCLA's Mechanical and Aerospace Engineering Department. The microhand can make a fist that can grasp objects smaller than a millimeter across. Check out the freaky video on the researchers' website of the microhand grabbing a blob that looks like a fish egg. The tiny hand is made of inert materials, making it ideal for handling gooey biological samples. Lu and Kim describe their microhand in a paper published October 16 in the journal Applied Physics Letters."
