Smart dust is a vision of the networked future where intelligent networks of trillions of miniscule sensors continuously feel, taste, smell, see, and hear what is going on in their surrounding environment, communicate with each other and exchange information. Smart dust networks are the ultimate Internet-of-Things (IoT) devices. Smart dust refers to wireless networks of sub-millimeter-scale autonomous computing and sensing platforms not larger than a grain of sand. Smart dust senses and records data about its environment such as light, temperature, sound, presence of toxins or vibrations, and transmits that data wirelessly to larger computer systems. https://www.activistpost.com/2023/12/smart-dust-what-is-it-and-how-it-used.html
