最近,“智能尘埃”(smart dust)的概念见诸媒体。始作俑者克里斯·皮斯特是美国加州大学伯克利分校的工程学教授,一个想要用尘埃覆盖整个世界的人。他把自己的公司取名为“尘埃”,每天都要生产一箱箱的尘埃运往全球各地。当然,它们绝非普通尘埃,而是一种由许多小型廉价智能无线传感器组成、尘埃之间可以相互通信的智能尘埃。由这些尘埃组成的独立网络几乎可以监测到地面上所有的信息,从气温、人群数量到交通流量,甚至包括地震的破坏程度和海鸟的健康状况。它们就像被派出的千千万万个默默无闻、不被察觉的哨兵,在地球 Recently, the concept of “smart dust” has been found in the media. Initiator Chris Pister is an engineering professor at the University of California, Berkeley, a man who wants to cover the world with dust. He named his company “Dust,” and produced a carton of dust every day for shipping around the world. Of course, they are no ordinary dust, but a smart dust consisting of many small, inexpensive smart wireless sensors that can communicate with each other. An independent network of these dusts can monitor almost all the information on the ground, from temperatures, the number of people to traffic, and even the extent of the earthquake and the seabird’s health. They are like sending thousands of unknown, undetected sentinels on earth
