Japan’s TV Scent Technology
"Televisions which pump out the smells of cookery on screen could become reality after developments by scientists at Keio University in Tokyo."
“The researchers said it would release a candy floss smell when the image shows a fairground and can even emit the briny scent of the seaside when people look at their holiday photos.
The technique uses printers to spray small amounts of scent rather than ink. Dr Kenichi Okada, of Keio University, Tokyo, told New Scientist: ‘We are using the ink-jet printer’s ability to eject tiny pulses of material to achieve precise control.’ Ink jet printers work when a pulse of current heats up a coil of wire and creates a bubble that forces a small amount of ink down a tube an onto the page at high speed.”
