I’m not an engineer, so almost everything in this teardown went straight over my head, but I would still highly recommend taking a look. The microscopic technology behind mobile technology is truly mind-blowing.
From what I can piece together, the electronic gyroscope works by vibrating a small amount of mass, and when the phone is moved or rotated, this mass is displaced into the X, Y, and Z axis, and which is detected by a very tiny processor through equally tiny capacitors. This data is then transmitted to the iPhone’s processor, and allows you to play games. It’s incredible to think of what will be possible in the future, if something like this is possible now.
