TOKYO People stopping to smell the roses can now take that sweet floral fragrance home with them or even send it to a faraway grandmother, thanks to a new gadget in Japan that records and replicates the world's odours.
The new device, developed by scientists at the Tokyo Institute of Technology, analyzes smells through 15 sensors, records the odour's recipe in digital format and then reproduces the scent by mixing 96 chemicals and vaporizing the result.
Creator Takamichi Nakamoto says the technology will have applications in food and fragrance industries where companies want to replicate odours. It could also, however, be a boon for the digital world, allowing smells can be recorded in one place by sensors in a mobile phone, for instance and transmitted to appreciative noses halfway around the world.
It could also aid on-line shoppers by letting people check out perfumes or flowers before they buy.
The sensitivity of the human nose is very good, Mr. Nakamoto said. But to some extent we can replicate the performance.
He said his machine, in the works since 1999, is the most advanced of its kind in the world, though a similar project is also under way at Keio University, also in Japan.
So far, however, the machine is too big to be portable it measures about the one metre by 70 centimetres.
Still, the breakthrough follows on the heels of a Japanese smellovision project that synchronized smells to movie scenes. That odorous endeavour was undertaken by NTT Communications Corp. and emitted smells from under seats in two movie theatres to accompany parts of the film The New World, a Hollywood adventure film.
Mr. Nakamoto's smell recorder has successfully recreated a range of fruit smells, including oranges, apples, bananas and lemons, but can be reprogrammed to produce almost any odour from old fish to gasoline, he said.
Making the 15 sensor chips, which pick up aromas and convert them to a digital formula, was the hardest part, Mr. Nakamoto added.
But the unit's large size is also limitation because the 96 odour-forming chemicals are contained in separate glass bottles. A more compact version, which includes only the sensors, can record smells but must be hooked up to the blender to regenerate them.
We also want to extend the range of smells, and then we can think about commercializing the system, Mr. Nakamoto said.
Mr. Nakamoto's team of 12 scientists have been collaborating with a Japanese perfume company that produces the raw ingredients for fragrances and with electronics companies interested in the sensor chip technology.
