Technology Overview

Reflected sun glares and traffic noises are annoyances to urban residents. Our active smart window can reduce the sun glare while our quiet glass can isolate outdoor noise and even absorb indoor sound reverberation. This new tunable window device can even sense the temperature and humidity change. This multifunctional window is as must to green building for improved urban livability.


Technology Features & Specifications

Our active smart window is a tunable optical diffuser that can switch between clear (81% clarity) and frost (2% clarity) for broadband of visible light. Our quiet window glass is a slim and transparent microperforated acoustic membrane resonator that can absorber above 80% of sound energy over a broader bandwidth (500Hz to 1000Hz) as compared to  a micro-perforated glass panel.


Potential Applications

This tunable optical diffuser provide on-demand privacy. It could also be handy as a tunable sun visor against sun glare while being good for cinematography lighting. This transparent microperforated acoustic membrane resonator can absorb isolate and absorb the conversion in offices during meeting.  Combination of the two also make quiet ceiling with tunable light diffusion. 


Market Trends and Opportunities

Without use of exotic materials, other than sun-block material and adhesive, this devices costs low, less than 10% of the price of PDLC, to make.  This low-cost device technology will make smart window common for home adoption, in addition to office and shop. We can license to know-how and patent to glass makers to promote common adoption of this technology.


Customer Benefits

This multifunctional window is a must to green building for improved urban livability, especially for the city with cluttered high-rise building and heavy traffics.
