Vapor Communications seeks to eliminate expected issues such as scent muddling by allowing plastic pellets with scents to be activated with air flow over the pellets allowing each scent to be personal. All of the products depend on the pellets within the oChip (the “o” is short for olfactory), and are grouped into families of similar aromas. The company is seeking to create over 300,000 distinct scents, each lasting for 1,000 uses, and costing around $2.
The oPhone Duo is a tabletop device that emits aromas based on how photos are labeled.
The Scentee is the simplest of the products, and has been around for nearly two years. The $70 product plugs into the iPhone’s headphone jack, which then converts the liquid fragrance cartridge into an aerosol, and is good for 200 sprays.
