We report a gas/odor release system based on a gated PDMS chamber array which is employed for rapid, repeatable, and reliable gas/odor release upon electrical actuation. Heating elements trigger the gas release by warming the gas-containing capsule. 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. The proposed X-Y matrix structured odor-release system has an array of gas/odor containers with rows and columns of electrical heating lines, in which only the intersecting cell (and no other cells) from many arrayed cells is allowed to pass beyond the threshold accumulation of gas/odor pressure to force-open the cell gate for gas/odor release. We have demonstrated multi-cell array operation of a PDMS gas/odor-release device. Further refinements include: coiled internal heating elements, reloadable odor cartridges, high-conductivity interconnecting wires, textured heating elements, and multi-media integrated timed release. Potential applications exted to all forms of personal or public media, advertising, perfume release, and any other aroma control.
