[* black] Let's continue unraveling the secrets of the trackpad, starting with the coils. | |
[* black] Underneath all that wire is a whole lotta nada. Well, there is a ferromagnetic core, but no surprises lurk beneath that glittering surface. | |
[* black] Old school retina trackpad and new comparison. The plate is mostly the same, the cables and such are different. | |
- | [* red] Touch sensor 1.0 |
- | [* orange] Touch sensor 2.0 |
- | [* black] Strain gauges probably! |

+ | [* orange] Click sensor 2.0 (magic?) |
+ | [* black] We're pretty sure the magic pressure sensors involved in the new Force Touch trackpad are tiny [http://en.wikipedia.org/wiki/Strain_gauge|strain gauges|new_window=true], mounted on flexing metal supports to detect the amount of force behind a click or press. |
