Wetsuit‑Integrated Artificial Gill
The primary challenge in designing a compact artificial gill is achieving the enormous membrane surface area (estimated-at 60–100 m²) required for sufficient oxygen transfer, all within a wearable form factor. This design integrates the Hollow Fiber Membrane (hfm) module directly into the back panel of a wetsuit, forming a streamlined dorsal extension approximately 14 cm thick. This configuration allows for high‑efficiency gas exchange without impeding swimming motion or requiring external gear.
1. The Principle of Extreme Packing
The core of the system is the Hollow Fiber Membrane…
- Fiber Scale: Fibers are incredibly fine…
- Packing Density: Commercial modules can achieve…
- Material: Highly permeable polymers…
2. Controlled Flow and Efficiency
The HFM module’s structure ensures controlled flow…
- Shell‑Side Feed: Seawater is pumped…
- Lumen‑Side Extraction: A slight vacuum…
- The “Wavy” Improvement: Helical fibers…
3. Wetsuit‑Integrated System Components
The apparatus is fully embedded into the wetsuit’s back panel…
- HFM Cartridge: Embedded into the upper back.
- Water Pump: Positioned near the lower spine.
- Vacuum Pump: Maintains negative pressure.
- Oxygen Concentrator: Compact PSA unit.
