APPARATUS AND METHOD FOR CREATING AROMA

An apparatus, composition, and method for generating odor on demand. The apparatus includes a dispersing mechanism with a plurality of blister pockets each including a releasable aroma. A triggering mechanism is in combination with each of the plurality of blister pockets and configured to separately rupture individual blister pockets to release a corresponding releasable aroma. A controller is in actuating combination with the triggering mechanism. The controller is configured to monitor for at least one predetermined stimulus to actuate the triggering mechanism. The stimulus can include a predetermined text, sound, image, and/or location generated by the electronic device. A smart material can be used for holding and releasing the aroma or other compound. The smart material can include a porous polymer matrix, wherein the porous polymer matrix releases the material upon an actuation of the triggering mechanism. The invention further includes an electrospun fibrous structure with a hydrogel material having reversible properties for controlled release of the aroma, and a functionalized group to enhance water retention capability of the hydrogel in air. A physical property is reversibly altered as a result of a stimulus to release a compound or aroma and subsequently returns to an unaltered state resulting in containment of any remaining amounts of the compound or aroma.
