Smart windows can change the opacity

New Delhi: Researchers from Harvard University have developed a technique that can quickly change the opacity of a window, turning it cloudy, clear or somewhere in between with the flick of a switch.

Previous technologies used in “tunable” windows relied on electrochemical reactions and were very expensive.

“However, the new technology uses geometry to adjust the transparency of a window which is a much cheaper option,” said David Clarke from Harvard’s John A. Paulson School of Engineering and Applied Sciences.

The “tunable” window is comprised of a sheet of glass or plastic, sandwiched between transparent, soft elastomers sprayed with a coating of silver nanowires, too small to scatter light on their own.

With an applied voltage, the nanowires on either side of the glass are energised to move toward each other, squeezing and deforming the soft elastomer.

Since the nanowires are distributed unevenly across the surface, the elastomer deforms unevenly.

The resulting roughness causes light to scatter, turning the glass opaque in less than a second.

“It’s like a frozen pond. If the frozen pond is smooth, you can see through the ice. But if the ice is heavily scratched, you can’t see through,” added postdoctoral fellow Samuel Shian in a paper that appeared in the journal Optics Letters.

“Because this is a physical phenomenon rather than based on a chemical reaction, it is a simpler and potentially cheaper way to achieve commercial tunable windows,” Clarke noted.

The team is now working on incorporating thinner elastomers, which would require lower voltages, more suited for standard electrical supplies. (IANS)

HUDs or Heads-up displays, display navigation for drivers as a clear picture estimated on the windows and have been included in more recent car models by manufacturers for example Rolls Royce, Audi Mercedes-Benz, Hyundai, General Motors, and Land Rover.

You can discover separate upgraded HUDs for $100 to $300; they generally project onto a clear screen that sits on the dashboard before your displays guidelines, windshield and engine alerts. Other companies have designed appears and smart phone applications that offer HUD abilities for even less, like the Hudway Glass for only $50.

  1. Seat Massagers and Heating Units

You can find out the built-in heating units in shape of heating pads in car seats, with the latest upgradation as the comfortable update has increased in reputation in the past few years, with heated seats are now almost in every new model today. They not only offer the seat-warmer, but they also offer the front-seat massaging and cooling abilities as well.

If your car did not have the upgraded seats, you should not worry about. You can upgrade your seat covers with the upgradation of various heating settings for low price only with $50 or less than. More innovative cushions can offer cooling and deep massages, while still charging less than $100.

  1. Vehicle parking sensors

Twisting in and out of small parking areas is extremely traumatic, and often lead to fender benders or scratched door. The latest vehicles can sometimes take the wheel for you with automated parking, but there’s an affordable way to add parking help to your present car.

Parking sensors generally stimulate when you move into reverse. Using sound waves, the sensors identify things and use increasing lighting and beeping to notify drivers when they are arriving close to reaching something.

In addition, while experienced professional set up is always a plus, several sensors do not need exploration or cabling, and they can be used at home. Just make sure they are suitable for your car before buying.

  1. Rearview camera

We cannot work the good remarks of rearview cameras enough; they have become essential protection equipment for nearly all vehicles. The National Highway Traffic Safety Administration will need them in all new vehicles after May 1, 2018. The reason is that, as rearview blind spot camera has decreased the accidents ratio of almost 90% each year.

  1. Wireless Bluetooth stereos

Nobody wants a solution for having a telephone, or more intense, an accident due to diverted driving. In addition, in today’s regularly connected world that makes Wireless Bluetooth abilities a fan favorite update.
