SONTE Film fits on existing windows, controls natural light settings and provides UV protection for energy savings.

There certain innovations which more often appear like an idea from sky. SONTE Film is so amazing in terms of approach and inspiration to be ranked on this list. 

According to the promoters, curtains ‘’have been around for
thousands of years without much improvement. The small advances that have been made, such as motorized shades and smart glass, can be extremely expensive and complex to install. With SONTE Film, we set out to revolutionize the industry of windows and curtains.’’

Therefore, SONTE Film is billed as the first ever Wi-Fi enabled digital shade that instantly switches windows from opaque to clear in less than a second.

It combines with a free smartphone app that allows users to turn SONTE Film “on” for see-through windows and “off” for opaque windows. Users can also use the app to control a room’s privacy and transparency setting.

It includes specs like:

Power: 110-220VAC

Current: 0.05 amperes per square meter (10.76 sq ft)

Power: less than 5 watts per square meter (10.76 sq ft) in the (on) transparent mode (no power is required in the (off) opaque mode)

Switching: less than 1 second

Operation: (on) transparent (off) opaque

Thickness: approximately 0.4mm

Viewing angle: more than 140 degrees

Light transmittance: On (70%) Off (5%)

Haze Coefficient: On (7%) Off (87%)

Operating temperature: -20C (-4F) to 70C (158F)  

 UV: absorbs more than 85% 

Infrared: reflects more than 70%

The project is available on Kickstarter, where you can support it.
