MessageToEagle.com - Technology develops all the time and almost everyday researchers come up with a new innovation.
Now, a team of researchers Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima from the University of Tokyo
have developed the thinnest known transparent display.
This innovative technology enables projection of images on soap bubble, but projecting an image onto soap
isn't as easy as it may sound.
"It is common knowledge that the surface of soap bubble is a micro membrane," lead researcher Yoichi Ochiai said.
So the researchers subjected the bubble's membrane to ultrasonic sound waves, played through speakers.
Sonic waves break up the surface tension, creating a texture to the bubble that becomes opaque, while reflecting
enough light to project a vivid image for viewers.
The display uses a special combination of liquids to create a more durable bubble, but the main ingredient is still soap.
"It allows light to pass through and displays the colour on its structure. We developed an ultra thin and
flexible BRDF [bidirectional reflectance distribution function] screen using the mixture of two colloidal liquids."
Achieving such a thin screen is possible due to the fact that the structure of the bubble can be changed using ultrasound.

Ultrasonic vibrations are used to produce images on the screen and control its transparency and texture.
Also multiple bubbles can be used together to display a 3D image.
"Our membrane screen can be controlled using ultrasonic vibrations. Membrane can change its transparency and surface
states depending on the scales of ultrasonic waves," Ochiai explained.
"The combination of the ultrasonic waves and ultra thin membranes makes more realistic, distinctive, and vivid imageries
This system contributes to open up a new path for display engineering with sharp imageries, transparency,
BRDF and flexibility."
To keep the bubble from popping, a colloidal mix made up of sugar, glycerin, soap, surfactant, water, and milk,
enables the surface tension to be strong yet malleable. You can pass your fingers through the bubble without
popping the mixture.
The bubble’s texture can be also altered depending on the frequency of the waves and the surface texture can be changed
to be rough or smooth at will. For example, an image of a ball projected onto the bubble makes change its external appearance
fro a rough to smooth ball.
Changing the frequency (the type of wave) emitted by the speakers will also alter the reflective property
of the screen, which is a characteristic that cannot be changed at will on modern day screens.
Also the transparency of the projected image can be changed
at will, by affecting the intensity of the reflection. In similar way, like when we change the transparency of an image
Alien World That Contributes To The Vision Of Hell
There is a strange alien planet orbiting an orange dwarf star in the constellation Monoceros
bordered by the constellations of Canis Minor, Gemini, Hydra, Lepus, Orion and Puppis and located 490 light years away...
it, is truly beautiful and relaxing!
Is Our Galaxy Squared?
To determine the true shape of our galaxy is a complex task.
The Milky Way keeps challenging astronomers who now say that some of our galaxy's spiral arms are straight rather than curved.
New research suggests that the shape of our galaxy is different than previously thought!
Flying Cars - Incredible Technology Of The Future
A flying car can travel on roads and can take off, fly, and land as an aircraft.
These vehicles have previously been seen only in science fiction
movies, but with new technology quickly emerging, flying cars are becoming reality. However, this does not mean you should sell your car just yet!
Millennia Old Astronomical Secret Revealed
In 1943, an ancient papyrus was bought by the Cairo museum.
It was written in Hieratic and although portions of it were eaten away by ants, it was a very precious ancient document.
The papyrus contained three separate books dealing with astronomy. One of the books was the Cairo Calendar, and now it reveals an ancient astronomical secret...
Big Bang Machine Discovers Unknown Particle
Physicists at Cern have not yet been able to confirm the existence of
the elusive "God particle", but they have nevertheless made another interesting discovery
Scientists announced that the Large Hadron Collider, often referred to as the Big Bang machine has detected an unknown particle composed of three quarks.
Star Trek Tricorder Now Available Online For Anyone To Build!
Imagine you can see what cannot be seen. Wouldn't you want to actually be able to see beyond the visible?
The good news is that from now on it will be possible to see things we have previously only dreamt of.
We certainly live in exciting times. More and more devices that have long been considered pure science fiction are now quickly becoming reality.
"Sacred" 1.7 Million Volt Light Of The Gods
Today, his cool experiment enables Zeus-like miracles!
For the ancient Greeks, the occurrence of lightning mean that Zeus, lord of heaven,
was often very angry and upset. God used to throw jagged, terrifying bolts of lightning, like spears of fire. This was for the ancients, a "sacred light".
Living Earth Simulator - Supercomputer Predicting The Future
In Douglas Adams book the Hitchhikers Guide to the Galaxy we encounter a machine called Deep Thought. It is the most powerful computer ever built. Deep Thought is capable of answering questions
concerning life, the Universe, and simply everything. Now scientists are planning to create a similar machine. It is called the Living Earth Simulator (LES).
Levitating Ball Defies Gravity
Incredible Technology Of The Future
"Any sufficiently advanced technology is indistinguishable from magic, " Arthur C. Clarke once said. This new invention is close to magic...
Scientists have invented a way to make objects levitate and defy gravity. At first glance it can appear like magic, but it is science.
As you can see this metal ball is actually suspended in midair!
