SmartDust

Smart Dust “motes” is a new revolutionary technology consisting of tiny, wireless sensors that when clustered together, “these motes automatically create highly flexible, low –power networks” These devices are able to perform a wide range of functions such as ; motion detection, light detection, temperature and humidity reading.

These sensors are available in different sizes; some are as big as a deck of cards or as small as a stack of few quarters. Dust mote battery life ranges from a couple of hours to about 10 years. This depends on the size and capability of the device.

A single Smart Dust mote has:

• A semiconductor laser diode and MEMS beam steering mirror for active optical transmission

• A MEMS corner cube retro-reflector for passive optical transmission

• An Optical receiver

• A single processing and control circuitry

• A power source based on thick-film batteries and solar cells.

SmartDust replacing human tasks

SmartDust is a revolutionary technology; it was “conceived” in 1998 By Dr. Kris Pister. Even though wireless already existed, nothing like the SmartDust had been ever seen before. The name SmartDust comes from how this tiny particle is capable of doing so many things. SmartDust has become very useful today and many organizations and industries are incorporating it. SmartDust today works as a device to detect motion, it is very common in the military where it is used to track enemy movement. Before SmartDust existed in the military had to take turns guarding and watching out for enemies close by. SmartDust technology has been replacing tasks that had to be done by humans. For example with SmartDust technology you can now walk out from a room and the SmartDust will automatically detect that there is no one in the room and will turn the lights off. Through the years and improvements in technology SmartDust will be able to do the unimaginable.

Advantages for Organizations using SmartDust

With the price of Smart dust on decline due to technology innovation, and its easy use and installation, applications of these sensors are seemingly without an end. “Smart dust has theoretical applications in virtually every field of science and industry”. Smart dust is being marketed for use in factories, homes, and public places and for commercial, military, medical, security, and ecological applications.

The U.S Military is using Smart Dust to develop an “advanced perimeter security system”. This system will help provide “persistent surveillance”. This system will be able to detect and track enemy movement in the military operation. Similarly Smart Dust technology is being used to provide low cost security systems to homes and offices.

Hospitals are also using Smart Dust technology to track the movement of their patients. This helps hospitals have constant surveillance of their patients and know exactly where they are.

Also, Smart Dust lends itself to energy saving initiatives. Now-a-days office buildings have hundreds of motes that sense light and temperature levels as well as determining when people walk in and out of a room. The Smart dust network would be able to detect when there is no one in the room and turn off the lights, or adjust the temperature when someone walks in the room. Many companies are using this technology to save costs.

Energy Company BP also uses Smart Dust technology to predict failures onboard machinery. “The firm placed, 160 motes near some of the ship’s equipment to measure things like vibration in the ship’s pumps, compressor and engines” The Smart Dust sensors are able to detect any unusual vibration or motion, and technicians would respond to any alert and fix the problem before it results in a serious condition.
As Smart dust technology become smaller, cheaper and longer lasting there is no doubt that more industries will incorporate this technology.

Disadvantage for Organizations using SmarDust

Just like there are advantages for organizations using SmartDust, there are also some disadvantages. For example SmartDus technology runs in very high power consumption, and the battery can last as few as a couple of hours. SmartDust is commonly used in the military to track enemy movement 24/7. Therefore SmartDust with low battery duration will not be very useful for surveillance.

The picture above is an example of a SmartDust that can detect a intrusion within a parameter of 50 meters. It is one of the cheapest and smartest on the market at around 25 cents.

Advantages and Disadvantages of Organizations using Blogs

Blogs can be used effectively as a word of mouth marketing tool. Blogs are an easy and cheap way to communicate and deliver information. For example many authors use blogs to promote their books without having to spend money on advertising. So basically blogs are very effective in promoting a product and even a service.

There are many advantages for organizations of using blogs. One of the advantages is that through blogs the consumer are better informed and also blogs are a way of sharing knowledge and information within an organization. Also blogs help interact with customers and help the organizations develop strong relationships and brand loyalty. Another advantage of blogs is that blogs can be a positive way of getting feedback. Once information is posted in the blog anyone who reads the post can reply and respond to it. This is a quick way for organizations to get quick feedback. In general, blogs are very useful to organizations because it is a cheap and effective way of communication and delivering information.

However, there are also some disadvantages for organizations of using blogs. Blogs are very hard to maintain because they constantly have to be updated and for organizations this could be very time consuming. Another disadvantage about organizations using blogs is that many readers or potential buyers might not find the information in a blog very reliable. The person reading the blog might be skeptical about the information.
