Transforming RFID Chips into Smart Dust

 

From U.S. Department of Commerce ... Why Nanotechnology for Smart Dust? Sensors are: Small, Cheap, Low Power, and Highly distributed...Nanosensors or Smart Dust functionalities can be incorporated into a size comparable to a grain of sand. These smart dust functions are: Filtration, Sample concentration, Chemical sensing, Biological sensing, Environmental stability, Internal referencing/drift correction, Remote identification, Remote interrogation (>100 m), Remotely triggered chemical processing, Targeted motion, and Collective behavior (swarming)...... “The Smart Dust project is probing microfabrication technology's limitations to determine whether an autonomous sensing, computing, and communication system can be packed into a cubic millimeter mote (a small particle or speck) to form the basis of integrated, massively distributed sensor networks.” ...Field trials with Smart Dust at SMER ... performed the first 19 field trials of porous Si “smart dust” and small wireless chip-based systems for detection of environmental pollutants. The field trials were performed in the Santa Margarita Ecological Reserve, over 24 hours, and involved two undergraduates, two high school students, a graduate student, and a post-doc. A simulant (ethanol) was successfully detected from a distance of 25 meters. Santa Margarita Ecological Reserve (SMER) , San Diego county CA ...
