Most micromachines act as transducers; in other words, they are either sensors or actuators.. Sensors convert information from the environment into interpretable electrical signals.
Bulk micromachining [1] is a process used to produce micromachinery or microelectromechanical systems (MEMS).. Unlike surface micromachining, which uses a succession of thin film deposition and selective etching, bulk micromachining defines structures by selectively etching inside a substrate.
It has also been used to construct micromachinery. As an offshoot of researchers attempting to further miniaturize microtechnology, nanotechnology emerged in the 1980s, particularly after the invention of new microscopy techniques. [4] These produced materials and structures that have 1-100 nm in dimensions. [4]
Microfabrication technologies originate from the microelectronics industry, and the devices are usually made on silicon wafers even though glass, plastics and many other substrate are in use.
Microtechnology is a set of processes, techniques and tools used to create structures having at least one dimension of a functional feature in order of micrometer (one millionth of a metre, or 10-6 metre, or 1μm), typically within the range of 10 −4 to 10 −7 meters and application of those structures in more complex systems.
Supmicrotech has concluded a partnership with several universities worldwide: Technische Universität, Vienne, Austria; Institut National d’Informatique, Alger, Algeria ...
The microfactory's main advantages are saving a substantial amount of space, energy, materials, time, and upfront capital costs. [5]Due to their reduced dimensions, microfactories are normally highly automated.
Much like their macroscopic analog, microstructures can be produced using rapid prototyping methods. These techniques generally involve the layering of some resin, with each layer being much thinner than that used for conventional processes in order to produce higher resolution microscopic components.
