Invisible electronics system

Till now i have introduced you with Organic Electronics where we talked about flexible electronic systems, now i am going to introduced you with Invisible or Transparent Electronics which is just a magic of materials and ofcourse technology. Actually all these new technologies are possible just due to research in advance materials, like conductive polymer material, transparent material....

Transparent Materials
Wide band gap oxide semiconductors are generally transparent in the visible region of spectra. Therefore Oxide semiconductors are very interesting materials because they combine simultaneously high/low conductivity with high visual transparency and have been widely used in a variety of applications (e.g.  touch display panels, solar cells, flat panel displays, heaters, defrosters, optical coatings, among others) for more than a half-century.

Transparent Electronics Technology

Transparent electronics is an emerging technology for the next generation of optoelectronic devices, where the approach is to make transparent thin film transistor, Liquid crystal displays, light emitting diodes,lasers etc.

Transparent Thin Film Transistors

Transparent oxide semiconductor based transistors have recently been proposed using as active channel intrinsic zinc oxide (ZnO). The main advantage of using ZnO deals with the fact that it is possible to growth at/near room temperature high quality polycrystalline ZnO, which is a particular advantage for electronic drivers, where the response speed is of major importance. Besides that, since ZnO is a wide band gap material (3.4 eV), it is transparent in the visible region of the spectra and therefore, also less light sensitive.
