Odor concentration refers to an odor's pervasiveness. To measure odor sensation, an odor is diluted to a detection or recognition threshold. The detection threshold is the concentration of an odor in air when 50% of a population can distinguish between the odorous sample and an odor-free reference sample.
Articles relating to odor, caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive by their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor.
Today's modern advancements in biotechnology and nanotechnology are enabling digital scent technology to assist several industry sectors, including the medical technology, nanotechnology sectors, [2] [3] as well the entertainment and fashion industry sectors, as perfumers are utilizing this technology on neurological, emotional and psychological levels.
Smell may refer to; Odor, airborne molecules perceived as a scent or aroma; Sense of smell, the scent also known scientifically as olfaction "Smells" , an episode of Bottom; The Smell, a music venue in Los Angeles, California; Code smell, any characteristic of a program that possibly indicates a deeper problem
The iSmell was also designed for use inside games and movies. The modular design of the iSmell allows a programmer to integrate smell activation files that will trigger the release of any smell or combination that they desire. If the user were to watch a movie with the digiscent files embedded, the user can smell the surroundings of each scene.
A simple algorithm that can be used for location estimation is the triangulation method (Figure 2). Consider the odor detection equation above, the position of the odor source can be estimated by organizing sensor distances on one side of the equation and ignoring the noise. The source position can be estimated using the following equations:
