An X–Y Addressable Matrix Odor‐Releasing System Using an On–Off Switchable Device

An olfactory factory: Using a novel polydimethylsiloxane (PDMS) elastomer-based device, the switchable release of specific gases is demonstrated. Heating elements trigger the gas release by warming the gas-containing capsule (see scheme). The release can be switched on and off by repeated thermal cycles. An X–Y addressable matrix of such capsules results in an odor-releasing system for multiple odors for virtual-reality applications.
