Batteries that last for years
While I was at a computer conference a while back I heard about "smart dust," which is tiny sensors that can be spread in an area to pick up temperature, humidity sound, weight, just about anything. I was quite intrigued but never really considered the power source for these specks of dusts.
An article in The Feature addresses powering these and other tiny sensors without needing to replace thousands of batteries. One particularly interesting topic is that of nanograss. It's a real geeky read, but impressive technology.
