Smart Dust

  1. 1. By – C.AVINASH
  2. 2.  The current ultramodern technologies are focusing on automation and miniaturization. Smart dust are tiny electronic devices designed to capture mountains of information about their surroundings while literally floating on air. The idea behind ‘smart dust’ is to pack sophisticated sensors, tiny computers and wireless communicators into a cubic-millimeter mote. As the motes drift on wind, they can monitor the environment for light sound and a wide range of other information and beam that data back to the base station, miles away.
  3. 3.  Smart Dust requires both evolutionary and revolutionary advances in miniaturization, integration, and energy management. Designers can use micro electromechanical systems to build small sensors, optical communication components, and power supplies.
  4. 4.  The smart dust mote is run by a microcontroller that not only determines the task performed by the mote, but consists of the power to the various components of the system to conserve energy. It also turns on optical receiver to see if anyone is trying to communicate with it. Microcontroller will use the corner cube retro reflector or laser to transmit sensor data or a message to a base station or another mote. Primary constraint in the design of the Smart Dust mote is volume. Add legs or wings to smart dust and we get micro robots.
  5. 5.  Miniaturization effort could help solve one of the most pressing economic problems of the day: run away energy costs. Sensors form a network relaying data. Save nations on electricity costs.
  6. 6.  Chemical or biological sensors. Weapons stockpile monitoring. Defense related sensor networks. Land or space communication networks. Monitoring environmental conditions that affect crops and livestock. Building virtual keyboard. Internal space craft monitoring.
  7. 7.  Research in the wireless sensor network area is growing rapidly in both academia and industry. Most major universities and many companies now have sensor networking projects, and some products are appearing on the market
