| Abstract |
The paper presents the fabrication and test of a micro scent injector module. A micro scent injector module consists of an injector fabricated by micromachining, a scent cartridge and a controller. If a scent injection signal triggers the controller, it heats the scent liquid in the injector chamber and a scent liquid is vaporized. The increased vapor pressure opens a normally closed boss valve, and the scent vapor is injected through the opened nozzle. The liquid volume injected by the fabricated module is about 1μell for one second at 2 W. |
