Sim, a armadura cibernética de Darth Vader também era seu sistema de suporte à vida. De Wookieepedia :
The armor's belt and chest plate held the controls for the life support system, ensuring that Vader's body received enough oxygen, nutrients, and medicine; through this system, Vader could endure nearly any environment, including the vacuum of space.
E:
The helmet created Vader's menacing growl due to his natural voice being very weak from vocal-cord damage, and contained neural needles that painfully connected with the top of Vader's skull and spine, to form one interconnected unit. Without these, Vader could not use his artificial limbs. The armor had ten protective layers, while Vader had four artificial limbs as a result of his injuries on Mustafar and at the hand of Dooku on Geonosis.
Vader foi colocado na armadura após ferimentos graves sofridos em um duelo de sabres de luz com Obi-Wan Kenobi:
A DD-13 Medical Assistant Droid fitted him with cybernetic implants while a 2-1B surgical droid picked away any remaining chars of clothing and flesh from the Dark Lord's body. An FX-9 Medical droid supplied Vader with blood transfusions during the surgery. Vader required a permanent breathing apparatus, a result of his encounter with the flames, altering his voice into a deep growl.
Além disso:
Darth Vader wore the armor for over two decades, until his redemption and death. He initially hated the armor, but after living with it for several years, he embraced how it isolated him from the rest of the galaxy, allowing him to concentrate on becoming a pure instrument of the dark side.
