[* black] Let's continue unraveling the secrets of the trackpad, starting with the coilscoils—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] Underneath all that wire is a whole lotta nada. Well, there isThe magnets rapidly push and pull against a ferromagnetic core, but no surprises lurkmetal plate mounted beneath that glittering surfacethe trackpad, to create a tiny "buzz" of feedback with each click and (and a slightly bigger bigger buzz for a "force click").
[* black] Old school retina trackpad and new comparison. The plate is mostlyMy how the same, the cablestimes have changed and such are differenthow far we've come. Back in our day it took a lot less real estate to sense a click.

[* red] Click sensor 1.0 (a button)
[* 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.
[* black] This works in conjunction with the traditional capacitative touchpad up top, to pinpoint where you're applying force.
