Usuario:Jondel/Polvo inteligente

Smartdust is a network of tiny wireless microelectromechanical sensors (MEMS), robots, or devices, installed with wireless communications, that can detect anything from light and temperature, to vibrations, etc.

El polvo inteligente es un red de sensor con comunicaciones inalámbricas y microelectromechanical(MEMS) , robot o dispositivo minuscula. Tiene funciona inalambrica y se puede detectar luz, temperatura, vibraciones, etc.

The devices are also called motes and are intended to shrink down to the size of a grain of sand, or even a dust particle. Each device contain sensors, computing circuits, bidirectional wireless communications technology and a power supply. Motes would gather data, run computations and communicate using two-way band radio with other motes at distances approaching 1,000 feet (300 metres).

Los dispositivos estan también se llaman los 'motas' y se piensan para contraerse al tamaño de un grano de la arena, o aún a una partícula de polvo. Cada dispositivo tiene sensores, circuitos que computan, tecnología de comunicaciones inalambrica bidireccional y una fuente de alimentación. Los motes recopilarían datos, funcionarían cómputos y se comunicarían con la radio con otros motes en las distancias que acercan a 300 metros.

When clustered together, they automatically create highly flexible, low-power networks with applications ranging from climate control systems to entertainment devices that interact with information appliances.

The Smartdust concept was introduced by Kristofer Pister (University of California) in 2001 1. A recent review 2 discusses various techniques to take smart dust in sensor networks beyond millimeter dimensions to the micrometre level. [edit]

Applicaciones

A typical application scenario is scattering a hundred of these sensors around a building or around a hospital to monitor temperature or humidity or inform of disasters, such as earthquakes. In the military, they can perfome as a remote sensor chip to track enemy movements, detect poisonous gas or radioactivity. In a hospital, they can be used to track patient movements. The ease and low cost of such applications have raised privacy concerns, primarily in science fiction stories.
