iFixIt have done the mother of all teardowns. Pairing up with Chipworks, they took the gyroscope from the iPhone 4, and ran it through an electron microscope.
The iPhone 4 uses what’s known as a MEMS gyroscope, which rely on tracking vibrations. How small of a scale is this whole thing used at? The final picture has a scale of 50 micrometers, which is half the thickness of a human hair.
More photos after the jump!






Wow… this is so damn cool!!
Yeah, I don’t understand any of this, but the imagery is spectacular!
