[* black] Let's continue unraveling the secrets of the trackpad, starting with the coils—we were hoping to find some evidence of linear oscillators in the taptic engine, but it looks like it's just a series of electromagnets. | |

+ | [* black] The magnets rapidly push and pull against a metal rail mounted beneath the trackpad, to create a tiny "buzz" of feedback with each click (and a second buzz for a "force click.") |
+ | [* black] So that explains the buzzing, but what about the sensing? |
[* icon_note] A patent issued [http://appleinsider.com/articles/14/01/21/apples-new-trackpad-patent-replaces-click-button-with-force-sensors-adds-tactile-feedback|last year|new_window=true] hints that the Force Touch might utilize strain gauges to measure pressure on its surface. | |
[* black] We're going to just have to crack this bad boy the rest of the way open to see if that's the case. |
