Exploring the Limits of System Integration with Smart Dust

The Smart Dust project aims to explore the limits of system integration by packing an autonomous sensing, computing, and communication node into a cubic millimeter mote that will form the basis of massive distributed sensor networks, thus demonstrating that a complete system can be integrated into 1m m 3 . Effectively exploring this space requires new approaches to design that emphasize energy and volume constraints over all others. To this end a 16 mm 3 autonomous solar-powered sensor node with bi-directional optical communication has been demonstrated, with smaller nodes forthcoming. System integration limits will shrink even further as carbon nanotube technology matures.
