Flexible Sealing Device Challenge

Description of Challenge: NASA is seeking a new sealing method or device to reversibly join the edges of flexible materials. The seal device will be integrated into an inflatable airlock, and utilized to facilitate extravehicular activity (EVA). This effort is a part of a new concept of  inflatable, membrane-based space modules, which can be  deployed when needed to provide expandable working and living space for astronauts. 

What types of approaches can be used to create an airtight seal between the edges of flexible fabric-like materials of these modules?  The sealing methods or devices need to be easy to use, light, flexible for storage, yet robust and reliable. 

Awards Available:  There is a guaranteed award. The total payout will be $15,000, with at least one award being no smaller than $7,500 and no award being smaller than $2,500.
