What the hell is "smart dust?"

Here’s what it has in the article below:

Smartdust is a system of tiny microelectromechanical systems that can detect light, temperature, vibration, magnetism, or chemicals. They are operated wirelessly on a computer network, can be used for medical or military surveillance purposes, and can be dispersed through the air via Chemtrails. Which would greatly go unnoticed by the sleeping masses who have come to accept them. When combined with the mesogen soft robot technology, which has already been found in several blood samples of unwitting victims, they could create a means of monitoring and controlling the entire human population.
