On chip motor is expected to become a new energy for portable products

MIT (MIT) a group of researchers shows that gas turbine based on silicon chips, and 25 cents coin size is ten times the battery operation time. The study shows a new energy source for portable electronic devices, in addition to ordinary batteries.

This micro motor is composed of 6 pieces of silicon wafer stacking and welding, the wafer by a single crystal and its atoms arranged. The wafers are made by the advanced etching process, and when they are stacked together, the surface of the wafer and the space between layers will produce the desired characteristics and functions.

So far, the research group has successfully made all the components in one wafer nearly 100 elements can be cut to form an independent unit.

Began in the whole process of micro combustion chamber, fuel and air in the rapid mixing and combustion. The researchers used high strength micro structural materials made of turbine blades, the speed of 20000r/s. The next step will be to integrate micro motors into the system.
