About our technology
Our technology is based on the fundamental principle of electrophoresis.
With principle of electrophoresis, we actively control pigment particles in an electric field, dispersed in a high-viscosity dispersion. When there is no power applied, the particles “float” against the surface, absorbing the light in the desired spectra. When power is applied, the particles are drawn against an electrode – as the size of the electrode is very small, this is invisible to the human eye and the window becomes transparent.
The picture is a schematic, not-to-scale drawing of the concept.
Our smart windows start switching directly, without delay. Our particles are color neutral, which means that black is actual black and switching to transparency takes place in neutral grey tints. Unless you prefer another color – anything is possible, as our switching glass is very versatile.
As our minimum transparency level is below 1%, we provide new ways of designing your facades and buildings. There is no further need for sun blind systems or curtains, no double cavities and double skinned walls: this does not only reduce cost and weight, it reduces maintenance and increases the level of comfort of the occupants of the building. On top of this, it decreases the amount of energy needed for HVAC and lighting, as the transparency level is fully tuneable.
We do not only promise you the best technology available – we also promise you that this technology will be available against affordable, more than cost competitive costs.
