Abstract
A controlled odor generator, comprising a central processing unit, at least one micropump unit, a sensor unit and a fan. The micropump unit is housed in a casing containing odorous fluid and has a micropump array for ejecting the odorous fluid in tiny droplets. The central processing unit regulates operation of the micropump unit, allowing to control timing quantity and mixture of spread odor. The sensor unit provides the central processing unit with environmental data, like temperature, air density and humidity, as well as human body states for controlling the micropump unit. Environmental changes are followed by a change of spraying of odor, and varying taste and demand are adapted to.
