Pesquisadores desenvolveram uma tecnologia que pode permitir que pessoas assistam a filmes em bolhas de sabão. Eles conseguiram alterar as propriedades da membrana da bolha de sabão, transformando-a no que chamaram de "o monitor mais fino do mundo".
Com isso, os cientistas acreditam poder incrementar a nitidez na projecção de imagens, até mesmo em 3D. Uma equipa internacional formada por especialistas de universidades japonesas e americanas usou ondas de ultrassom para tentar transformar a textura da membrana transparente em uma superfície opaca, onde pudessem ser projectadas imagens.
Um dos coordenadores do estudo, Yoiki Ochiai, disse à BBC Brasil que este é somente o início da pesquisa. "Nossa invenção pode contribuir para o desenvolvimento de um monitor, que pode mudar as propriedade de reflexão da superfície (da bolha)", conta.
Ele declarou ainda que o seu trabalho é diferente dos realizados anteriormente: "Nossa tela feita de membrana pode ser controlada usando vibrações ultrassónicas. Membranas podem mudar a sua transparência e o estado das superfícies dependendo das escalas das ondas sonoras emitidas. Baseado nisso, nós desenvolvemos diversos aplicativos com a membrana, como uma tela em 3D".
Os cientistas adicionaram substâncias à tradicional mistura de água e sabão para tornar a membrana da bolha mais resistente - e evitar que ela estoure bem no meio da parte mais interessante do filme. "Este sistema contribui para abrir um novo caminho na engenharia de monitores com imagens mais nítidas", conta Dr Oichiai em seu blog.
A equipa disse ainda que a descoberta pode ser útil também para artistas que querem dar uma sensação mais realista nos seus trabalhos em museus, e até mesmo para mágicos. Anteriormente, outros pesquisadores haviam feito tentativas de desenvolver monitores pouco tradicionais como uma tela de computador feita de água e um touchscreen de gelo.
Researchers have developed a technology that can allow people to watch movies on soap bubbles. They managed to change the membrane properties of soap bubble, turning it into what they called "the world's slimmest monitor."
Therefore, scientists believe they can increase the sharpness in the image projection, even in 3D. An international team of experts formed by Japanese and American universities used ultrasound waves to try to transform the texture of the transparent membrane on an opaque surface, where they could be projected images.
One of the coordinators of the study, Yoiki Ochiai, Brazil told the BBC that this is only the beginning of the study. "Our invention can contribute to the development of a monitor, which can change the properties of reflection from the surface (bubble)," he says.
He further stated that their work is different from the previously performed: "Our screen made of membrane can be controlled using ultrasonic vibrations. Membranes can change its transparency and the state of surfaces depending on the scale of the emitted sound waves. Based on this, we developed several applications with the membrane, like a screen in 3D. "
Scientists added substance to the traditional mix of soap and water to make the membrane more resistant bubble - and prevent it from bursting in the middle of the most interesting part of the film. "This system helps to open a new path in engineering monitors with sharper images," says Dr Oichiai on your blog.
The team also said that the discovery may also be useful for artists who want to give a more realistic feeling in his works in museums, and even magic. Previously, other researchers have made some attempts to develop monitors as a traditional computer screen made of water ice and a touchscreen.
