Microfabricated Biomimetic Artificial Gill System (MBAGS)

Military operations in underwater and high altitude environments impose significant restrictions on the warfighter's ability to meet operational objectives. An advanced breathing apparatus that mimics the efficiency, simplicity, and durability of the gill-swim bladder found in fish could greatly improve human maneuverability and sustainability in both aquatic and high altitude settings. In this Phase I Small Business Technology Transfer (STTR) program, Infoscitex and Case Western Reserve University propose the development of a biomimetic synthetic gill design based on the subdividing regions of clef, filament, and lamellae found in natural fish gills. Computational modeling will be performed to identify design parameters required for efficient gas exchange. A biomimetic oxygen carrier material will be incorporated into a thin, gas-permeable membrane to facilitate gas exchange. In Phase I, gas exchange units will be designed and demonstrated for rapid, efficient extract of oxygen from surrounding water. The Phase I team includes a leading developer and manufacturer of breathing equipment for military and commercial end-users.
