Apple’s latest gadget, the iPhone 4, features a electronic MEMS gyroscope within its shiny shell. But how does that little chip work, and what does it do, well read on the find out and be amazed.
According to Wikipedia’s definition, “A gyroscope is a device for measuring or maintaining orientation, based on the principles of conservation of angular momentum.” The emphasis is on measuring or maintaining orientation, which is the exact reason an iPhone 4 contains one of these gizmos and was touted by Steve Jobs.
A mechanical gyroscope – like the one shown below on the left- uses a spinning rotor in the center to detect changes in orientation.
The iPhone 4 utilizes a microscopic, electronic version of a vibrational gyroscope ( shown above right ), called a MEMS gyroscope.
Check out few additional microscopic photos of electronic MEMs gyroscope below.
iFixit partnered with Chipworks to bring you an in-depth look into the science behind these micro-scale gyroscopes. Click here to read the full in-depth illustrated tear down review.
