Microscopic Robot Tweezers

Developed at the University of Toronto, these microscopic tweezers are just a few millimeters wide in any direction. What really sets these apart from current technology is the fact that these tweezers can sense when they are about to collide with something, and they also monitor how much squeezing force is being applied to them.

The picture above is magnified eighteen times, so you’d probably need a magnifying glass just to get a good look at it. Because of these minuscule dimensions, the tweezers are computer controlled. In fact, they can be attached to a microscope and left to function on their own without human interaction.
