congeries

UCSD researchers fabricate 'smart dust' particles
dust-sized chips of silicon that allow them to rapidly and remotely detect a variety of biological and chemical agents

'Smart dust' makes sense of environment
grains of silicon that spontaneously assemble, orient and sense their local environment, marking a first step toward the development of robots the size of sand grains

Data gathering on a speck of dust
tiny electronic devices designed to capture large amounts of information about their surroundings while literally floating on air
