Really tiny wireless sensor node

This paper published in Biology Letters is linked to a video that shows a WSN attached to the belly of a dragonlfy. It weights 300mg (battery included) and apparently dragonflies do not have a problem carrying it around.

This is made by a guy called Jim Cochran who runs Sparrow Systems with his dad — they both sound like very nice people and from the look of it they can build stuff that works (rather than the usual WSN vaporware).

    I am suprised by the weight, but also by the battery duration – more than 12 days for such small batteries ?!
