Digital Smell: Toward Electrically Reproducing Artificial Smell Sensations

نویسندگان

چکیده

Artificially reproducing smell sensations, without using chemical odorants, would change the future multisensory internet experiences. This article presents a computer-controlled reproduction technology proposed for stimulating human olfactory receptors, weak electric pulses. We developed concept prototype that can generate rectangular-shaped electrical pulses in different frequencies (0–30 kHz), duty cycles (0–100%), and currents (1–5 mA). is tested by middle nasal concha region of 31 healthy participants. During our studies, 8 participants reported fragrant sensations stimulation parameters 1 mA with 70 Hz. For 10 Hz, sweet sensation, while 6 sensations. The key novelties this paper include: 1. describe development first computer controlled digital device receptor neurons, 2. Testing new on subjects including were not previously tested, 3. Recording intensities 22 types (smell-related non-smell-related) could be produced stimulation. 4. investigate users’ perception usefulness type technology.

Scent engineering: toward the goal of controlling how flowers smell.

Floral scent has an important role in the reproductive processes of many plants and a considerable economic value in guaranteeing yield and quality of many crops. It also enhances the aesthetic properties of ornamental plants and cut flowers. Many floral scent volatiles fall into the terpenoid or phenylpropanoid/benzenoid classes of compounds. Although the biochemistry of floral scent is still ...

The intentionality of smell

If any sense modality represents, vision does, but argument is needed to show that smell does. This paper rebuts two reasons for doubting that smell represents, and offers several arguments that it does. The paper then considers several recent proposals as to exactly what a smell represents, and defends a version of the author's original proposal-that a smell represents a miasma in the air-agai...

Computer - Controlled Smell Output

Computer-controlled scent output technologies have a history dating back nearly 50 years. However, it’s only in the last few years that such systems have become easy to use and readily available, fueled by the emphasis on multimedia technologies from the internet and dot.com boom and by the increasing prominence of fragrance in everyday life. The key advantage of computer-controlled output, in ...
