Smell-O-Vision Has Pleasant Aroma For San Diego Researcher
Monday, June 27, 2011
SAN DIEGO Sight and sound TV seems so last century. It seems the future of enhanced sensory entertainment could soon be smell-o-vision.
Movies like the “Scent of a Woman,” or a pizza commercial, can be seen and smelled according to Sungho Jin, Ph.D., a San Diego professor who was approached by Samsung Electronics to develop a smell-o-vision device.
Jin, a researcher at UC San Diego's Jacobs School of Engineering said he and his graduate students developed a prototype than can emit up to 10,000 odors.
It works like this: Tiny compartments inside the device contain scented liquids that spray into the air when triggered by a preprogramed electrical signal.
“We send electrical current to the chambers and that heats up the interior. When the temperature goes up so does the internal chamber pressure which pushes the vapor out of the device and into the air,” explained Jin.
He also said the palm-sized aroma emitter is adaptable and mobile.
“The device can be attached to a TV or made small enough to be on a cell phone. It can also be placed on the walls inside a movie theater,” said Jin.
When the liquids dry up or the smells fade, the chamber is replaced like an ink cartridge on your printer, said Jin.
A few details still need to be worked out, like how to cleanse the air in between fragrance spurts. And, overcoming smell-o-vision’s stinky past will also take some effort.
