To work at great depths, deep-sea divers use pressure suits with built-in biomechanical exoskeletons. A durable carcass made of nanomaterials can protect individuals from high pressure. It also helps them feel stronger by augmenting their movements. The suit maintains a stable body temperature, compensating for changes in the surrounding water. Modified microorganisms in a special tank can supplement stored oxygen; they produce a special air mix and regulate pressure inside the suit.
