Technology And It's Use

Whats is technology 

From the Greek tekhnologia, meaning systematic treatment or science of craft. Applied science. Practical arts.The application of scientific devices, machines, and techniques for manufacturing and other productive processes.


Origin of technology 

Greek tekhnologiā systematic treatment of an art or craft tekhnē skill ; see teks- in Indo-European roots. -logiā –logy


What is Microtechnology 

Microtechnology is the use of compact, or very small, technical devices. Microtechnology embraces microcomputer parts, space microdevices, microsurgery, and microelectronics. Both microfilm and microfiche, which store information on film, are also examples of microtechnology; microfiche generally stores more than microfilm. The term micro, derived from the Greek word mikros, meaning small, is used to describe something that is unusually small.

Microtechnology has emerged in various technological fields since about 1920. Advances in scientific knowledge and applications of that knowledge make microtechnology possible. Specific concepts and inventions have provided the necessary basis for microtechnology. These significant inventions include the microscope,electricity , computers, and lasers. For example, microscopes allow technicians to view minute regions of computer microprocessors and components of other microdevices. Microscopes also enable surgeons to view aspects of a patient's body at a resolution not possible for the naked human eye.



Microtechnology in medical 

With the publishing of technologies to fabricate and mass-produce microscale tools and micromachines, microsurgery stands to potentially benefit through the development of a fundamentally new class of instruments. These new instruments may provide the surgeon with access to the smallest reaches of the body and perform operations that are currently not possible with manually operated tools. These new devices can be variably constructed and configured based on a wide range of design possibilities and can be built to serve many different fundamental surgical functions requiring the manipulation and handling of small tissues and structures, including grasping, cutting, and monitoring. With these functionalities also comes a high degree of integration, allowing tools and space to be used efficiently. Adapted from the techniques of the microelectronics industry, the fabrication methods and materials produce structures that are mechanically strong and easy to reproduce on a large scale. Well-developed design and physical modeling tools mean that the process of instrument development and validation can be streamlined. Along with these new instruments comes the need to provide automated interfaces to effectively translate human operator intentions into the appropriate actuation and motion of these devices. These interfaces must include the capability to scale down human motions to the range of microns. Most likely, the operation of these new microsurgical devices will resemble the control schemes developed for robotic surgery. The control schemes will provide accurate motions while minimizing the chances of damaging tools or unnecessarily injuring tissues. Naturally, these new tools and surgical schemes will require a transition from the conventional paradigm. However, with new surgical capabilities that may allow direct intervention into the inner workings of a cell, MEMS (Micro-Electro-Mechanical Systems) and nanotechnology-based tools may become a crucial part of the arsenal for the next generation of surgeons. Invariably, future developments of this new class of instruments will depend in large part on needs identified by the surgeon and an understanding of the enable properties of microtechnology. 


Laser  Laser microtechnology has many applications. Machines can use laser light to read or scan information. Bar code scanners in grocery stores routinely register product identification and cost with laser scanners. Lasers are also used to cut materials such as cloth and to weld metals. In addition, lasers (particularly CO2 lasers) are used in medicine. Lasers are used surgically and for specific medical applications like shattering gallstones. Laser beams guide weapons, such as missiles, that contain laser designators that can detect and follow the laser light path. Some lasers are as small as a grain of sand.

Uses of Micro Technology in Computer

Electronic Numerical Integrator and Computer was the first electronic general-purpose digital computer. It was Turing-complete, and able to solve "a large class of numerical problems" through reprogramming. It weighed more than 30 short tons (27 t), was roughly 2.4 m × 0.9 m × 30 m (8 ft × 3 ft × 98 ft) in size, occupied 167 m2 (1,800 sq ft) and consumed 150 kW of electricity. From that time to till date many inventions done on computer to reduced its size and increase speed and storage and engineer  got success in this. Its happen because of micro technology used in computer. Not long after the computer was invented, engineers began to make improvements that increased computer functions and decreased computer size. Today’s computers contain many microcomputer components— the primary one is the microprocessor, a type of microchip. A microprocessor contains the entire computer central processing unit on a single chip. Microchips come in a range of sizes and generally are smaller than 0.08 sq in (2 sq mm). Microcomputers are embedded in and control numerous modern devices such as automobiles, digital watches, telephones, and video cameras. The microelectronic circuits of these embedded computers are called integrated circuits.


Space microtechnology 

      Any device sent into outer space must have certain characteristics. It must be able to withstand the stress of propulsion into space. It must also be able to use power efficiently. In addition, it must be able to operate under thermal extremes. It is also very favorable for such devices to be as small and lightweight as possible. Several space microdevices have been created that meet these criteria. Miniature gas chromatographic ionization detectors, ion mobility spectrometers, x-ray diffraction devices, and fluorescence instruments are all in various stages of development. Each of these devices plays an important role in exobiology, the science of extraterrestrial environments that may support life.
