Here’s how the U.S. Air Force wants to hunt the next generation of its enemies: A tiny drone sneaks up to a suspect, paints him with an unnoticed powder or goo that allows American forces to follow him everywhere he goes — until they train a missile on him.
On Tuesday, the Air Force issued a call for help making a miniature drone that could covertly drop a mysterious and unspecified tracking “dust” onto people, allowing them to be tracked from a distance.
The solicitation floats the idea of dropping a “dust-like” cloud of electromagnetic signal-radiating taggants, either on top of the target or in his path so that he’ll walk into it.
DARPA is even looking into “smart dust” which is essentially a cloud of dust mote-sized sensors that could be sprayed into the air near a target in hopes that he or she might walk through the cloud and be tagged, meaning the drone or delivery system wouldn’t even have to make direct contact with the target (think bird-like drones that can crop dust a vehicle or person)
Some Pentagon ideas include marking targets with biological paints or micromechanical sensors
Microelectromechanical systems (MEMS) are small integrated devices or systems that combine electrical and mechanical components. They range in size from the sub micrometer (or sub micron) level to the millimeter level, and there can be any number, from a few to millions, in a particular system. www.csa.com...
A new microelectromechanical-systems capacitive pressure sensor with extremely high sensitivity (2.24 F/kPa) is introduced. The sensor essentially consists of a small drop of mercury and a flat aluminum electrode that are separated by a 1 m-thick layer of Barium Strontium Titanate (a high dielectric-constant ceramic). The assembly constitutes a parallel-plate capacitor where the surface area of the electrodes is variable to a high degree. The mercury drop is pressured by a small corrugated metal diaphragm. As the electrode area of the parallel-plate capacitor varies, a total change in capacitance of more than 6 F is obtained.
Of course, the Air Force also notes that the technology it is fostering will be useful for things like tracking wildlife, though why anyone would want to fire a hellfire missile at a flock of migrating birds is unclear.

ok why am i the only one who thought of this
pretty useless if it rains.
ah tax dollars at work

yeah they do but a mini drone "crop dusts" people i am not so sure about.
however anything is possible
id rather see it used to the gitmo detainees plant them all and then let them all go home
and then take em out
