since its birth， micro nano manufacturing industry has been considered that it will come in handy in solving the earth crisis. Now， nano / skin-type satellite， biological medical gene sequencing chip， smart wearable devices， smart dust， beauty skin care nano 3D cell printing and others has turned out to be "xiangbobo"（a favorite）. We live in a world that is more efficient， more intelligent， more green with micro nano manufacturing！

This period "Knowledge is Power" will show you the amazing changes brought about by"micro" in spacecraft， Bio Medical， smart phones， new materials and other fields as well as how the current leaders of science and technology transform the world around usfrom micro scale and nano scale.
