Some of their findings: The iPhone 4 utilizes a microscopic, electronic version of a vibrational gyroscope, called a MEMS gyroscope. A microelectromechanical system MEMS is an embedded system that integrates electronic and mechanical components at a very small scale.

The GK10A is comprised of a plate, called the "proof mass," that vibrates oscillates when a drive signal is applied to set of drive capacitor plates. More nanotechnology: MEMS gyroscopes can feature amazing oscillator designs, such as this Kionix gyroscope. You'd never see it because it's under a dust cover - but that's good, because on this scale a single human hair micron thick would ruin its functionality.

A MEMS oscillator with the outer casing removed: an ASIC, with its custom gate array, sits on top of the oscillator, which is bonded to it by the obvious wires. The two are then encased in plastic to make the chip.

At this scale, a human hair is as wide as the central item. That's nanotechnology in everyday life - achieved through the advances in microengineering.

Alternatively, you could just carry a full-sized gyroscope in your pocket. But after seeing these pictures, would you want to? Topics Apple. Toggle navigation.
