The n54 medical implant, as seen in Episode 13: Questions.
The n54 medical implant is a device developed by HPlus Nano Teoranta, designed to "track 25 key processes of the human body," including:
- blood flow
- heart rate
- vascular pressure
- adrenal secretion
- oxygen intake
- digestion
- bone growth
- circulation
- excretion
- heart regulation
- maintenance of tissue moisture
- thyroid secretion
- nutrient absorption
- salivary secretion
- carbon dioxide removal
- ocular transmission
- cochlear transmission
- cellular repair
- immune system response
- detoxification
- protein synthesis
- homeostasis regulation
- insulin production
- nervous system response
- respiration
It is 86 nanometers in diameter, has a protein-based design that is self-forming, and is implanted via saline injection (the starter materials are injected and self-assemble in the body). The device was designed to monitor many processes of the human body and "act as an early warning system for sufferers of over a dozen diseases."
The device is a predecessor to the later HPlus Implant, and many of its medical functions were incorporated into that device.
