It is a fact that among the goals of those skilled in science and technology is not only making things smart, but also affordable; and shows, the method developed by a team of researchers from the Massachusetts Institute of Technology (MIT) that could be seen as a key piece for the manufacture of cheap smart windows.
Delving into the proposal, it is worth mentioning that it is based on an experimental plastic called polydimethylsiloxane or PDMS, which when it is at rest is completely opaque and does not let light through, but when it stretches or inflates, the opposite occurs. All this, based on the Beer-Lambert Law, a classical optical theory that describes the way in which light travels through a material with given properties.
The MIT team combined that theory with their experimental analysis to derive a simple equation with which to predict the amount of light transmitted through a mechanically deformed PDMS structure.
Now, and taking the MIT report on this project as a reference, the structure of the experimental plastic and its predictive understanding could be useful in the design of more economical materials oriented to the production of cheap smart windows They will also cooperate in energy saving both in domestic and professional environments.
In future, then, designers will use the MIT group equation to determine the amount of force to apply to a polymer layer and effectively tune it to the amount of incoming light.

Without detracting from the innovative proposal of MIT, it is also worth remembering the technique patented by the Higher Council for Scientific Research (CSIC) and developed by a team from the Madrid Institute of Materials Science, focused on reducing production costs from cheap smart windows.
This technique is based on the use of thin films of highly porous material as a coating to control the amount of light that passes through a glass.
