Smell Liquid MEMS Vaporizers are used for digital smell technology which senses transmits and receives scent-enabled digital media, such as web pages, video games, movies and music. A vaporizer mainly composes: a silicon substrate, a micro-channel array, a membrane suspending over the micro-channel array and supported by the silicon substrate, a resistance heater and a resistance temperature sensor are disposed on the membrane. Since the vaporizer is a silicon-based integrated actuator which provides advantages including small size, compact structure, lower power consumption, lower cost, increased reliability, higher precision, and more environmental friendliness.

Smell consists of many different molecules, e.g.: the aroma of coffee is made up of 20 various molecules. Nonetheless our nose perceives only 15 molecules which are enough to identify the smell as coffee. The physiology of smell in humans begins in the nasal cavity. There, a huge number of receptors (over 40 million) are located in the upper roof of the cavity. When the molecules reach the receptors, an electric impulse is sent directly to the brain and establishes a direct connection between our sense of smelling and our brain.

Smell is the sense closest linked to memory. Studies have shown that people can remember a scent with 65% accuracy after 1 year while visual memory sinks to 50% after only a few months.  The smells we experience play a crucial role in how we associate with memories and places. Have you ever come across a whiff of something that instantly takes you back to an old memory? Whether it reminds you of your mother’s cooking or a childhood trip to the ocean, a distinctive scent sinks into your brain and stays there.

Smells can evoke powerful emotions. The perfume industry is built around this connection, with perfumers developing fragrances that seek to convey a vast array of emotions and feelings; from desire to power, vitality to relaxation. It is likely that much of our emotional response to smell is governed by association, something which is borne out by the fact that different people can have completely different perceptions of the same smell. Take perfume for example; one person may find a particular brand ‘powerful’, ‘aromatic’ and ‘heady’, with another describing it as ‘overpowering’, ‘sickly’ and ‘nauseating’. Despite this, however, there are certain smells that all humans find repugnant, largely because they warn us of danger; the smell of smoke, for example, or of rotten food.  

Healthcare professionals are aware of the powerful impact of scent on patient feelings of well being. Studies have shown that scent can be used in many applications to positively affect the behaviors and emotions of patients, family, caretakers, and healthcare staff.

Vanilla, lavender and neutralizing scents (“Pure”) are popular recommendations. Vanilla can reduce claustrophobia in MRI facilities, calm pre-surgery and dental patients, and can reduce patient cancellations. Neutralizing unpleasant odors for patients with a heightened sense of smell will also soothe and comfort. Citrus uplifts and helps ease anxiety.

Clearly Better Scents offers custom fragrance development developed for the unique needs of your hospital, nursing home, doctor’s office, dentist’s office, outpatient surgery facility, laboratory physical therapy or chiropractic facility.

Senses of smell can even affect productivity in office environments. Specific smells have been found to increase alertness which in turn results in higher productivity rates. One study found that when lemon oil was diffused throughout a Japanese office building, productivity among data entry operators increased by 54%. Scents can also be used to ward off mid-afternoon brain fog by revving your concentration levels.

It is may be supplied that smells can influence our perception of time. In one of the studies, 20 separate participants were exposed to a baby powder aroma, a coffee aroma, and no aroma at all. While the coffee aroma produced a reduced perception of time, the baby powder aroma produced a longer perception of time. Likewise, pleasurable fragrances have been shown to create “dwell-time” in stores, increasing the likelihood of customers making purchases.

In summary with the smell liquid MEMS vaporizers the digital smell communication will soon influence your everyday life.
