WERE DOING SPECBIO STUFF AGAIN BABY. Feels fucking good to get back to my roots (i get to close 50 tabs worth of research now. Delightful)

Terminators are made of a Titanium Alloy (Im going with ferrotitanium which is a mix of iron and titanium. They never specify in the movie what the titanium is mixed with so fuck it we ball baby)) skeleton contains limited amounts of Mimetic Polyalloy (fake material used for the terminator in terminator two). Mimetic polyalloy can be hard or flexible and will be used to create new structures that the iron collected from food will later fully establish. This will allow his metal endoskeleton to mimic standard growth that a regular skeleton would have growing up.

When first introduced to the foster system (medical checkups are required once entering the foster system. The police probably do some checkups on Robbie also just to make sure hes okay when they find him), medical tests show that he has anemia, so it’s  recommended he be put on iron supplements. My reasoning is any iron in his blood is almost instantly sent to work on growing his endoskeleton. That means the actual amount of iron left in his blood is pretty low (the opposite of this is hemochromatosis which is when there's too much iron in your blood). I could see him probably trying to stop iron supplements but I think there would be some side effects to convince him to start taking them again. His joints might ache or I could see child terminator Robbie saying some mildly concerning shit like ‘my bones feel hungry’. I also think he might crave foods that are high in iron. Like beef/chicken liver, canned tuna, and seafood. Idk how frequently he could AFFORD these things but yk. The endoskeleton hungers eternal  ¯\_(ツ)_/¯

Nanobots are used to repair wiring for his nervous system, synthetic muscular system, acts as his immune system and sometimes accelerates healing for his organic systems (organic parts of his muscular system, skin, and nerves). For the most part his organic systems heal on their own at about the same pace as a normal human person. Nanomachines/nanoparticles are fueled by glucose (if Robbie needs work done by the nanobots he might need to eat or crave sugar both before and afterwards). 

He probably has a fairly (?) normal digestive system and circulatory system. The spread of his circulatory system is just more limited because some parts of him don't really need blood. . The primary job of the nanomachines when they aren't busy healing or growing his body is to harvest as much heme iron from the food/supplements he consumes as possible so that it can be repurposed later. His immune system is taken care of by the nanobots so all he has to worry about is red blood cell and plasma production. Similar to adults, most of this takes place in his spine, ribs, skull and breastbone. The red bone marrow is stored inside these metal parts and the red blood cells are then released into his bloodstream. Plasma is created in the liver and also in bone marrow so most of that stays the same

Another fun bit about the endoskeleton:

Bones close to his skin that are in danger of being exposed (knuckles, kneecaps, cheekbones) have a very thin enamel coating to preserve the illusion that they are bones. But underneath it’s all just the same Ferrotitanium.

onto the muscular system

Muscles are laced with a Shape Memory Alloy called Nitinol. A flexible (SURPRISINGLY durable godamn) metal material made of nickel and titanium that reacts to electrical and thermal impulses. It’s already used in the medical field (I can not fucking BELIVE that this is real thats so so so SO fucking cool). Superficial muscles are more organic (80% muscle 20% nitinol) but as the muscles go deeper they become more and more synthetic (20% muscle 40% nitinol 40% titanium wiring for durability). Superficial muscles are more muscle for stealth purposes. If injuries go deeper than anticipated he will still be able to fly mostly under the radar, assuming no wires have been significantly dislodged. If he’s been injured into the deeper layers then there’s no use in trying to lay low anymore. He’s clearly in a combat situation and stealth protocols no longer matter.

ALSO I did some math to try and figure out how heavy Robbie would be with all this metal in his system. Heres the logic for my equation:

CONTENT WARNING. MATH.

About 12 - 15% of your body mass is bone. A person weighing 155 lbs will have about 22lbs of bones. One Cubic centimeter of bones will weigh about 1.85 grams.

Ferrotitanium alloy is 4.5 grams per cubic centimeter. 

The equation 1.85/4.5 = 22/x in which x is his new bodyweight. Multiply 1.85 by 2.43 to get 4.5. Because the equation must be symmetrical you then multiply 22 by 2.43 to get 53.5 lbs.

With all of the extra metal in his system, I think it would be reasonable to assume that he LOOKS like he should be about 155 lbs but his actual weight is around 250 lbs. I have. NO idea how doctors are going to deal with this.

Had some VERY FUN hypotheticals from @moosemonstrous (thank you for proofreading my insanity once again <3) about his body shedding as much water as possible and like. shriveling his organs to drop as much weight as possible before doctors appointments. But given that he is a cyborg and not an android I do think that might kill him so Im thinking??? Maybe people just assume the scale is broken.... every single time he's in.

IDK man if they have access to his wack ass file then his breaking the conservation of mass is the least weird thing in there.

OKAY YAYYYYY NOW THAT I HAVE HIS INTERWORKINGS LAID OUT I CAN DO FUN CYBORG GORE!!!!! <33

Nickel Titanium: A Revolutionary Material with Unique Properties

Nickel Titanium, also known as Nitinol, is a remarkable metal alloy with unique properties that have revolutionized various industries. Composed of nearly equal parts nickel (Ni) and titanium (Ti), this alloy exhibits extraordinary characteristics, such as shape memory and superelasticity, which have made it invaluable in applications ranging from medical devices to aerospace engineering.

Key Properties of Nickel Titanium

Shape Memory Effect (SME): One of the defining features of Nickel Titanium is its shape memory property. This means that the alloy can "remember" its original shape and return to it after deformation when exposed to a certain temperature. This property is due to a reversible phase transformation between two crystal structures: martensite and austenite.

In its lower-temperature martensitic phase, Nickel Titanium is soft and deformable.

When heated above a certain transformation temperature, it transitions into its austenitic phase, regaining its pre-deformed shape.

Superelasticity: Nickel Titanium also exhibits superelasticity or pseudoelasticity, which allows it to undergo large deformations and return to its original shape without permanent damage. Unlike ordinary metals, Nitinol can stretch significantly (up to 10 times more) and return to its previous form. This ability makes it ideal for applications where flexibility and strength are critical.

Corrosion Resistance: Nitinol is highly resistant to corrosion, especially in biocompatible environments, such as the human body. This makes it an excellent material for medical implants and devices, as it minimizes the risk of corrosion-related complications.

Biocompatibility: Due to its nickel and titanium composition, Nitinol has excellent biocompatibility, making it suitable for long-term use in medical devices such as stents, guidewires, and bone anchors.

Applications of Nickel Titanium

Medical Devices: Nitinol has found widespread use in the medical field due to its unique properties. Some of its most common applications include:

Stents: Nitinol stents are commonly used to treat narrowed or blocked arteries. Their superelasticity allows them to expand in the body without requiring surgery, and their shape memory enables them to conform to the natural shape of the blood vessels.

Orthodontic Archwires: Orthodontic devices like braces use Nitinol wires because of their ability to return to their original shape after being deformed, applying consistent force over time.

Surgical Instruments: The flexibility and durability of Nickel Titanium make it ideal for minimally invasive surgical tools.

Aerospace and Automotive Industry: In aerospace and automotive engineering, the need for lightweight, strong, and durable materials is critical. Nitinol is used for actuators, fasteners, and damping systems because of its shape memory properties, which allow for automatic adjustments in shape when exposed to temperature changes.

Consumer Products: Beyond industrial applications, Nitinol has made its way into everyday products. For example, Nitinol eyeglass frames can return to their original shape after being bent, making them both durable and comfortable.

Robotics and Actuators: Nitinol's shape memory and superelasticity properties are also advantageous in robotics. Nitinol-based actuators are capable of precise movements and can respond to temperature changes, providing more efficient and versatile options for robotic systems.

How Nitinol Works: The Science Behind It

The key to Nitinol's extraordinary properties lies in its unique phase transformation behavior. At lower temperatures, Nitinol exists in a martensitic phase, where it can be deformed easily. When heated, the material transforms into its austenitic phase, in which it regains its original shape. This phase transformation is driven by changes in the crystal structure of the alloy.

Martensite Phase: In this phase, Nitinol has a lower symmetry structure, which allows it to be easily deformed. The alloy retains this deformed state until it is exposed to a temperature above the transformation threshold.

Austenite Phase: When heated above a critical temperature, the structure becomes more symmetric and rigid, and Nitinol returns to its original, undeformed shape.

The temperature at which this transformation occurs can be finely tuned by altering the ratio of nickel to titanium, allowing engineers to customize Nitinol for specific applications.

Future of Nickel Titanium

The versatility and unique properties of Nitinol continue to open new doors in various fields. Ongoing research is focused on improving its performance and finding new applications for this revolutionary material. Innovations in manufacturing and processing techniques are expected to further enhance its properties, such as refining its superelasticity and making it more cost-effective for widespread use.

In the medical field, advancements in Nitinol-based devices are leading to more sophisticated minimally invasive procedures. Similarly, in aerospace and robotics, Nitinol is likely to play a key role in developing more efficient, lighter, and smarter systems. As the world pushes for more sustainable and high-performance materials, Nickel Titanium is set to remain a critical material for the future.

Nickel Titanium, or Nitinol, stands out for its unique combination of shape memory, superelasticity, and biocompatibility. From medical devices that save lives to cutting-edge aerospace components, Nitinol's influence is vast and growing. Its versatility and potential for innovation make it a material of the future, one that will continue to shape technology and industry for years to come.
