Sometime in May 2000, there was news from Israel's Weizmann Institute( a research centre with a reputation for scientific and technological breakthroughs.)Under their system a person could send an 'encoded' message from one computer to another, then translated to a sensor which would release chemicals imitating the smell."

Then there was news of NTT in japan to have displayed a costly demonstration with smells of atural oils, such as eucalyptus, sandalwood and basil.(It cost around 10000USD)

Plus there were many news from all parts of world of work going on in this project.
And now news from from Tokyo Institute of Technology.
We've been hearing threats of smell-o-vision for decades now, but it looks like engineers at the Tokyo Institute of Technology are getting serious about an odor recorder that can analyze scents and reproduce them by combining the 96 chemicals packed inside the device. Not only will it be able to approximate the smells of the finer things of life such as freshly-baked bread or apple pie, but it could also help doctors to diagnose remote patients by whipping up a hell of a stench with smells of urine, bile and rotten egg farts.

You point the device at an object, and then it records its odor using 15 chemical-sensing microchips, or electronic noses. It can then transmit that data to another device in a different location, or save it for later playback. So far, the system has been able to accurately record and play back the scent of orange, lemon, apple, banana and melon, and it's said to be able to demonstrate the difference in scent between a red and green apple.

The researchers hope to implement the device for online shopping, where you'll be able to smell before you buy, and also in various virtual-reality environments. As they are with all technological innovations, we're thinking the porn industry will lead the way with stank-ho-vision. –
