Technology for an apparatus using dissolved oxygens for underwater breathing without an oxygen tank for a long time

 

Client / Market

  • Underwater disaster rescue equipment, underwater exploration equipment, scuba diving equipment, submerged scooter, underwater activity equipment, the platform for supplying underwater oxygens

Necessity of this Technology

  • When using an oxygen tank, underwater activities are allowed only within the time
    limited by the oxygen tank capacity.
  • Long-hour underwater activities such as underwater rescue activities for an
    emergency marine disaster or underwater explorations require multiple oxygen
    tanks, which leads to make many limitations due to its volume and weight.

 

Technical Differentiation

  • This technology does not require an oxygen tank, enables underwater breathing
    using dissolved oxygen in water
  • When developed as a small portable design, it is expected to be utilized in
    various areas such as human rescue, transportation means, disaster prevention,
    aquanautics, leisure activities, and military activities in water.
  • By minimizing the energy consumption, oxygens can be supplied from water for
    long hours.
  • Underwater breathing apparatus technology using dissolved oxygen in water
    without an oxygen tank
  • This technology reduces power consumption by increasing surface area
  • Continuous treatment of gases emitted from breathing for reuse
  • Improving dissolved oxygen separation rate using magnetic materials
  • Underwater breathing with an oxygen tank limits underwater activity time due to
    its tank capacity; using dissolved oxygen in water enables long-hour underwater
    activities

 

Excellence of Technology

  • Lab mic subjected to an experiment using 500 mL/min dissolved oxygen separation
    technology survived for 50 minutes underwater
  • As an academic presentation, published on J. of Membrane Science, Sensors and
    Actuators A: Physical etc.
  • Development of artificial gill technology for underwater breathing without an oxygen
    tank (Electronic Times, Dec. 11, 2011) reported
  • 2 principal researchers and 2 senior researchers were participated in the research.
