"Researchers are working hard to reduce the size and cost of sensors, so they can be combined with RFID devices that can be linked in an ad hoc network. Because the sensors will be inexpensive and linked wirelessly, they'll be able to cover a broad area. At Sandia, researchers are putting the final touches on the Rapidly Deployable Chemical Detection
System (RDCDS), the U.S. government's planned key tool for sensing the presence of hazardous substances in public places. The system, which is funded by the U.S. Department of Homeland Security, is designed to provide rapid and effective protection at venues that attract large numbers of people."
