Gyroscope in Apple phone

[Loose rivets]

Just looking at a news item about the innards of an Apple phone. One of the many chips was an ST Micro gyroscope. It's flat, so how many axes can this accommodate, and indeed, how does it work, i.e. light, massif wheels, little green men?

One never ceases to be amazed . . . even more so by the fact that the plural of axis is axes.

It's a MEMS device that uses a proof mass rather than any spinning bits. Displacement is detected capacitively.
