Smart dust is a technology involving nano-scale sensors and electronics embedded in dust-sized devices that can detect things like temperature, light, and movement. The devices communicate wirelessly and are very inexpensive to produce, costing around $0.62 each. Potential applications include environmental monitoring, habitat monitoring of animals, military surveillance, medical uses such as detecting damaged cells, and more. The technology was first conceived in the 1990s and continues to progress with potential to gather various types of data.
