Smart Curtains Respond To The Presence Of Light

Smart Curtains Respond To The Presence Of LightSmart houses, smart cars, smartphones, here and now we are presented with the idea of smart curtains. Hmmm, how exactly does that work? Smart curtains do not need you to actually get up from your favorite lounging chair to close or open it, as it has the capabilities of preventing too much light from coming in whenever it is exposed to light. This was made possible thanks to the efforts by the folks over at the University of California Berkeley, who have managed to come up with a new kind of material that allows the nanotubes embedded within to activate whenever they are exposed to light.

    Invisible Beam Created By Scientists

    Invisible Beam Created By ScientistsThe quest for an invisibility cloak has been the stuff of legends for a long time already, with varying levels of success. The thing is, here we are with another development that touches on the topic of invisibility – but an invisible beam is the subject matter in question now. Scientists from the University of Singapore could very well have come up with a more refined invisibility solution, calling it a “beam of darkness” which will be able to envelop objects, where in turn, it would make them invisible to the naked eye.

    There is one major issue, however, as majority of the metamaterial invisibility cloaks out there will only be able to function with a tiny range of frequencies of light. When used at the wrong frequency, the cloak could be actually self-defeating, ending up as more visible even so. Needless to say, the scientists are currently working to improve on that situation, which means that a true invisible beam has yet to be achieved. I suppose that in due time, their efforts will be able to pay off, and chances are the military would want to dip their fingers in it as soon as possible. Imagine cloaking an entire platoon of tanks that roll up to the enemy’s borders without them knowing. Now, if only there was a way to cloak sound…

    Accidental Discovery Leads To Electrical Conductivity Boosted By 40,000%

    Don’t you just love to hear stories about accidental discoveries in the world of science that actually changed the way we see the world, as well as bring some benefit to mankind? Take the discovery of penicillin for example, if Dr. Alexander Fleming threw away that petri dish, it might have taken a few more years (and many more lives lost along the way) before penicillin was discovered. Well, in the 21st century, Dr. Marianne Tarun, who is a postdoctoral research associate at Washington State University, has managed to accidentally discover that the conductivity of strontium titanate crystals happens to gain an increase by as much as 400% for days after being exposed to room lights.

    This particular discovery certainly has its fair share of positive benefits as well as possible applications, especially in the realm of computer memory and various kinds of electronic devices. This serendipitous discovery was made after a sample of strontium titanate was left on a table counter prior to conductivity testing. Strontium titanate is a kind of crystal used in jewelry, just so you know what it is. This particular effect that was discovered has been labeled as “persistent photoconductivity”. Hopefully this discovery will lead to better and more efficient electronics down the road.

    Makeup Gets Conductive

    Makeup Gets ConductivePutting on makeup might not be the same any more in the future, as wearable technology takes on a whole new level of interactivity. With the clever application of conductive makeup in common beauty items such as false eyelashes, nails and eyeshadow, computer scientist Katia Vega managed to figure out a way to make conductive elements as well as sensors part of transforming an ordinary makeup into gadget-activating remote controls.

    Whenever the eyeshadow is applied to both the top and bottom of the wearer’s eye, if you were to take longer than 0.5 seconds to blink, sensors within the eyeshadow and metallized fake lashes will hook up and complete a low-voltage circuit. This would then be able to launch a miniature drone in theory, activating an LED headpiece in other applications, with one’s imagination being the limit. For instance, how about other low-voltage applications such as switching a musical track or a presentation image?

    Of course, there would also be other experiments by Vega that involved the use of false nails, so that the wearer is able to be a DJ by controlling the music with just the surface of a pool of water alongside one’s nails. Is the age of the Hunger Games coming?
