摘要： A multi-layer control device or one-way valve (100) includes: a first layer (10) having at least one first opening (12) formed therein; and a second layer (20). The first and second layers are joined together such that at least one channel (24) is defined therebetween, which channel selectively permits gas flow from the first opening out of the device/valve. In operation, the valve selectively opens to permit gas flow through the channel in response to a pressure differential on opposing sides of the valve, wherein the pressure differential sufficient to open the valve (ΔΡ 0 ) dynamically varies over time. Suitably, a material is arranged in the channel which experiences a change that precipitates the dynamic variation of ΔΡ 0 .
