#6 Micro Bee

The device is microbot that imitate a bee.  Developed at the Harvard Microrobotics Laboratory, the Mobee, which stands for "Monolithic Bee" can buzz around performing tasks such as surveillance -- or even pollinizing plants. Harvard's mechanical bee weighs about as much as a real one, about one tenth of a gram, is about the size of a quarter, and, like a real insect, has a pair of fluttering wings, a thorax, and stabilizing halters, small structures which operate like gyroscopes. Mobee is equipped with a battery, microprocessor, sensors, transmitter, and antennas and is made from 18 layers of different materials that assemble like a child’s pop-up book.

#7 Smallest Capacitors

Capacitors are vital parts of most of electronic circuits, be it TV, Smartphone or other computing circuits. Engineers at Japan's Murata Manufacturing have created one of the smallest discrete capacitors around. Made of monolithic ceramic, the tiny capacitor measures .005 x .005 x .01 inches, smaller than a pencil point and one-quarter smaller than the previous record for capacitor size; it should be available later this year.
