Pixie dust

Pixie dust is the informal name that IBM is using for its antiferromagnetically-coupled (AFC) media technology, which can increase the data capacity of hard drives to up to four times the density possible with current drives. AFC overcomes limits of current hard drives caused by a phenomenon called the superparamagnet effect.
AFC allows more data to be packed onto a disk. The pixie dust used is a 3- atom thick magnetic coating composed of the element ruthenium sandwiched between two magnetic layers. The technology is expected to ....etc

ABSTRACT
Advances in hardware technology has enabled very compact, autonomous and mobile nodes each having one or more sensors, computation and communication capabilities ,and a power supply. The Smart Dust project is exploring whether an autonomous sensing, computing, and communication system can be packed into a cubic-millimeter mote to form the basis of integrated, massively distributed sensor networks. It focuses on reduction of power consumption, size and cost. To build these small sensors, processors, communication de ....etc

ABSTRACT
The ËœSmart Dustâ„¢ project is aiming to build an autonomous sensing, computing, and communication system packed into a cubic-millimeter mote, to form the basis of integrated, massively distributed sensor networks. So, this device will be around the size of a grain of sand and will contain sensors, computational ability, bidirectional wireless communications, and power supply, while being inexpensive enough to deploy by the hundreds. Smart Dust requires evolutionary and revolutionary advances in integration, ....etc

Smart dust is tiny dust size device with extra-ordinary capabilities. Smart dust combines sensing, computing, wireless communication capabilities and autonomous power supply within volume of only few millimeters and that too at low cost. These devices are proposed to be so small and light in weight that they can remain suspended in the environment like an ordinary dust particle. These properties of Smart Dust will render it useful in monitoring real world phenomenon without disturbing the original process to ....etc

WHAT IS A SMART DUST?

Autonomous sensing and communication in a cubic millimeter

Berkeleyâ„¢s Smart Dust project, led by Professors Pister and Kahn, explores the limits on size and power consumption in autonomous sensor nodes. Size reduction is paramount, to make the nodes as inexpensive and easy-to-deploy as possible. The research team is confident that they can incorporate the requisite sensing, communication, and computing hardware, along with a power supply, in a volume no more than a few cubic millimeters, while still achieving ....etc

Definition
The current ultramodern technologies are focusing on automation and miniaturization. The decreasing computing device size, increased connectivity and enhanced interaction with the physical world have characterized computing's history. Recently, the popularity of small computing devices, such as hand held computers and cell phones; rapidly flourishing internet group and the diminishing size and cost of sensors and especially transistors have accelerated these strengths. The emergence of small computing elements, with sporadic connect ....etc
