Seems like a fertile area to watch and when the timing is right, invest.
"No one has yet come close to making components small enough for smart-dust systems. But a concept known as mesh networking has reduced the power requirements, at least theoretically, to the point where researchers expect to produce, within the next few years, networks of sensor nodes the size of postage stamps powered by coin-size lithium batteries.
In such networks, sensors would need only enough power to communicate with their neighbors. Messages would be passed along to a more powerful control station or central computer.
All this has whetted the interest of investors looking for the next big thing in technology. A market research firm in San Diego, ON World, estimated that wireless sensor networks generated less than $150 million in sales last year but will top $7 billion by 2010."
"Futuristic though it may seem, the movement has captured the interest of venture capitalists, whose investments are supporting start-up sensor networking companies like Millennial Net, Crossbow Technology and Ember."
