ABSTRACT:
An adaptive membrane structure is provided. The adaptive membrane structure has movable membranes that can be made to change its gas, liquid or particulate permeability in response to surrounding environmental conditions. Such adaptive membrane structures can be used to provide protective apparel that is comfortable to wear wherein the level of protection provided is based on conditions in the environment. The adaptive membrane structures can be used to provide protective enclosures.
