Five unique output devices
Devices that can revolutionize your life !
FLL is similar to Electro-static speakers which have been around for years, but these are more efficient, smaller, lighter, and flexible. So, they can be used in advertising with audio posters, wrapped around corners, mounted in a car's ceiling, or hidden behind a painting.This technology operates at approximately 10% of the power consumption of conventional loudspeakers.
2. The Personal 3D Viewer
3. Talking paper
Researchers from Mid Sweden University have constructed an interactive paper billboard that emits recorded sound in response to a user's touch.
The prototype display uses conductive inks, which are sensitive to pressure, and printed speakers.
The team envisages that the technology could be used by advertisers, and in the future, it might even be employed for product packaging.
4. 3-D CHOCOLATE PRINTER
Believe it or not, a 3D printer that uses chocolate has been developed by University of Exeter researchers - and it prints layers of chocolate instead of ink or plastic.
Although still a prototype, several retailers have already expressed interest in taking on the device.
3D printing using plastic and metal is already widely used in industry to speed up design work.
The process involves using short laser pulses to erase words and images by heating the printed material to the point that they vaporise.
The researchers say it works with commonly used papers and toner inks and is more eco-friendly than recycling
"When you fire the laser, it hits the thin toner layer and heats it up until the point that you vaporise it," the team's lead author, David Leal-Ayala told the BBC.
"Toner is mostly composed of carbon and a plastic polymer. It's the polymer in the toner that is vaporised.
