When Tony Stark wants to use his nanotechnology armor he needs to touch his chest to activate the armor.

But Spider-Man and Black Panther don't need to do that.

They control it through their own mind.

So why does Tony Stark need to touch her chest to activate her?

You might think it's because he didn't have that technology.

However, he was the one who made Spider-Man's armor.

So he could have added it to his.

But the reason is much simpler than you might think.

In Iron Man 3 Tony ends up having post-traumatic stress while sleeping.

And his armor connected to his mind ends up trying to hurt his wife by his side.

Thinking she was an enemy

So he took this technology away from him so that when he has an anxiety attack again he doesn't end up making another mistake with someone he loves.
