Problems solved by technology

However, the yield of the traditional process is very low, which means that the finished belt cannot meet the quality assurance test under high rate or too high rate.
Moreover, conventional production processes cannot conveniently fabricate substrates sensitive to multiple gases

Embodiment Construction

[0020] discussed below Figures 1 to 7 , and the various examples used to illustrate the principles of the invention in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the invention. Those skilled in the art will understand that the principles of the invention may be implemented in any type of suitably arranged device or system.

[0021] figure 1 An example system 100 for producing a gas sensitive substrate according to the present invention is shown. Such as figure 1 As shown, a substrate 102 is unwound from a first reel 104 and one or more gas sensitive materials are deposited onto the substrate 102 by a dispensing unit 106 . The substrate 102 then enters the drying unit 108 , which dries the one or more gas sensitive materials on the substrate 102 . The substrate 102 is then rewound onto a second spool 110 .

[0022] Substrate 102 comprises any suitable material capable of receiving and retaining a gas s...

Abstract

A method includes forming a gas-sensitive substrate (102, 102a-102c) during a production process by dispensing (708) one or more gas-sensitive materials onto the substrate and drying (712) the one or more gas-sensitive materials on the substrate. The method also includes adjusting (720) the production process based on one or more sensor measurements associated with the substrate and / or the production process. Adjusting the production process could include conditioning (706, 710, 716) air around the substrate so that the conditioned air has one or more specified characteristics and adjusting (720) the one or more specified characteristics based on the one or more sensor measurements. The one or more sensor measurements could include one or more measurements of a moisture content of the substrate. Adjusting the production process could also include adjusting (720) a tension of the substrate. The one or more gas-sensitive materials could be deposited in multiple regions (202-206, 302-306, 402-408, 510a-510d) of the substrate, such as along multiple tracks extending lengthwise down the substrate.
