An artificial wearable gill

Rebreather diving equipment used by professional divers can be prohibitively heavy and clumsy to transport. It also has limited capacity, which in turn limits dive time. Amphibio is developing a super-hydrophobic porous membrane to create an artificial wearable gill. The material allows oxygen to pass from water into the breathing chamber inside the gill, and permits carbon dioxide exhaled by the diver to pass back into the water, thereby replacing the need for diving helmets and oxygen tanks. This patent-pending design is expected to have application in a number of fields.
