An electrical current is sent through the lead wires to heat an aqueous solution. The heat builds pressure, causing a tiny hole in an elastomer to open, releasing the odor, which is measured by the detector.

Researchers at the University of California at San Diego are collaborating with Samsung to develop a compact odor-generating component for TVs and cell phones. The as-yet-unnamed device would give television programs and Web sites a palette of 10,000 odors.
Sure, people have been trying to add smell to visual media for a long time (Smell-O-Vision anyone?). The UC San Diego-Samsung collaboration, however, is pushing the technology closer to reality. Miniaturization and digitization are cracking the big challenges of odor-on-demand systems: control and variety.
Odor pixels are the key: a 100x100 matrix of tiny wires will make it easy to heat any one of 10,000 tiny liquid-filled containers.
It'd be cool to catch a whiff of ocean during a beach scene, or take in the heady odor of woodsmoke as a campfire flickers onscreen. But I'm thinking the smells have got to be totally natural. Otherwise, the intense pine forest experience I'm expecting might turn out to be a subliminal cue to break out household cleaning products. Maybe Samsung could offer an eco-organic version.
