ELECTROTHERMAL HYBRID MICROSYSTEM FOR CONTROLLED DISPENSING OF FRAGRANCES AND AROMAS

The present patent belongs to the air deodorizer sector and concerns micro-manufacturing microsystems (10) which integrate multiple functionalities including electrothermal actuators (80) and radio frequency transmitters/receivers (RF), as well as microsystems responsive to wireless radio frequency signals and the micromanufacture of microsystems that control the release of fragrances and/or aromas (F) activated through the precise control of variations in temperature, by activating thermal resistance activated via wireless.The microsystem (10) simultaneously integrates a thermal electronic system (80), a wireless electronic transmitter/receiver system (RF), an electrical power supply system (60) and at least one compartment or well (50) for storage of the fragrance and/or aroma (F), all micro-manufactured on a support (30) of reduced thickness; the electrothermal system (80) comprising a set of conductors (40), interconnected with a set of resistors (R1) printed on the micro-manufactured support within the space or well (50) delimited for the deposition of the fragrance (F); the power supply system (60) being mechanical electrical power generators or light generators or chemical generators; the storage compartment for the fragrance and/or aroma being open or semi-sealed or sealed by membranes (M1); and the fragrances and/or aromas being in free form or associated with other supporting materials such as solvents or waxes or gums or silicas.
