Digiscents iSmell

In Oakland, Calif., DigiScents, Inc. is developing a digital scent device, called the iSmell. They are fully aware of how people will respond to the device's tongue-in-cheek name. The iSmell can create thousands of everyday scents with a small cartridge that contains 128 primary odors. These primary odors are mixed together to generate other smells that closely replicate common natural and manmade odors. The scent cartridge, like a printer's toner cartridge, will have to be replaced periodically to maintain the scent accuracy.
