For some reason, certain smells can trigger memories and
feelings. A person may smell a specific odor or aroma from the past and vivid
memories of the event and people involved will suddenly come alive in the
brain. Imagine capturing that memory triggering smell just like you can capture
a photograph. The odor recorder is a new hardware device that can record a
target odor and then reproduce it at any given time. This device was created
because it could benefit a variety of
fields: e-commerce, game, virtual reality, cinema, medical clinic, fragrance
creation, flavor creation, artistic expression, etc.
The odor recorder project was first started in 1999 by
engineers at the Tokyo Institute of Technology in
The odor recorder works by first introducing the target odor to be recorded. It then is sent to the PC with control application software and the PC uses fifteen chemical-sensing microchips or electronic noses to determine the qualitative and quantitative composition of the target smell. This calculation is modified into a digital recipe that is sent through the solenoid valve to a sensor array that is composed of multiple quartz crystal microbalance (QCM) sensors with a variety of coatings. A broad range of scents are then used to construct the digital recipe from a selection of ninety-six non-toxic chemicals. Certain chemicals are selected, from the 96 choices, depending on the target scent that is desired. The applicable chemicals are dropped into vials and mixed together. After being heated and vaporized the desired smell is produced.
“A quartz crystal microbalance (QCM)
measures mass by measuring the change in frequency of a piezoelectric quartz
crystal when it is disturbed by the addition of a small mass such as a virus or
any other tiny object intended to be measured. It can work under vacuum or
liquid environment thus making it useful to determine the properties of
polymers and adhesion of proteins. Frequency measurements are easily made to
high precision; hence, it is easy to measure small masses” (www.wikipedia.com).
“A piezoelectric
quartz crystal gives the ability to generate a voltage in response to applied
mechanical stress. When the crystal is subjected to an externally applied
voltage, it can change shape by a small amount. This is found useful in “applications
such as the production and detection of sound, generation of high voltages,
electronic frequency generation, microbalance, and ultra fine focusing of
optical assemblies” (www.wikipedia.com).
This device has successfully produced such scents as orange, apple, lemon, peach, and banana. Thus far, thirty-two odors in their vapor stage can be implemented in the odor recorder. By mixing the current scents, the device is able to produce a smell that gives off the aroma of mixed fruit.
This device will open up the barrier that faces many online shoppers. The barrier of not knowing what a product smells like before buying it. Items such as flowers, incense, potpourri, and even foods can be smelled right from your computer. The problem of ordering a product without knowing the scent will be solved. This would increase online shopping, which would increase revenues for businesses.
Also, the odor recorder will allow doctors to smell the scent of bile, blood or urine odors. This aspect, whether stomach turning or not, is a breakthrough for the medical field. This will aid doctors in the area of diagnosing patients. Paul Marks, journalist for NewScientist.com, states that the device will “even assist military doctors treating soldiers remotely.” The doctors treating our soldiers will be able instantly smell the aromas that relate to the patient’s symptoms or current state to aid in a faster diagnoses which could save lives.
In addition, this smelling instrument will add to the effects of virtual gaming. All the gaming industry thrives for is to produce the most realistic game. By incorporating this device with a game that has realistic graphics, it will allow users to feel like they are actually inside the game. Just imagine being able to smell all that you see while playing the game, such as gun smoke, trash in the streets or burnt rubber from your car tires. The odor recorder will give a whole new meaning to virtual gaming.
Technology already allows us to use two of our five senses. Not to long ago it was unimaginable that we would be able to see the person we were talking to on the phone. Now we are pushing those boundaries again by devising this hardware that will implement a third sense into our electronic uses. Just picture yourself in a movie theatre. The scene is a coffee shop and you can smell coffee just like you were there. This technology will revolutionize the world we live in.
