Defying physics with TG0 Technology — finding the loophole to the Faraday Cage effect.
The Problem with Physics
If you ask a standard electrical engineer to put a touch sensor behind a solid slab of stainless steel, they will likely look at you like you've just asked them to square a circle.
Why? Because of a minor complication called the **Faraday Cage effect**.
In the world of traditional capacitive touch, sensors work by detecting the subtle electric charge from your finger — but metal is conductive, it loves electricity. When you place a metal sheet over a capacitive sensor, the metal absorbs and scatters that electric field, effectively blinding the sensor. It's a Faraday Cage: a shield that blocks the signal completely.
For decades, this forced designers into a corner. If you wanted metal, you had to cut holes for buttons, or use fragile, paper-thin foils that felt cheap.
The TG0 Loophole: Don't Sense the Spark, Sense the Bend
We didn't break physics — but we did find a loophole.
While metal blocks electric fields, it cannot block Newtonian mechanics. When you press on a piece of metal, even a thick, solid block of aluminium, it bends. You can't see it with the naked eye, but it happens.
TG0's Metal Sensing technology ignores electricity. Instead, it detects **micron-level deflections** in the material itself — movements as small as one-tenth the width of a human hair.
By using a smart polymer sensor behind the metal, we can track exactly where and how hard you are pressing.
- No electrical field required - No cut-outs required - No "special" metal required — standard CNC-machined material works just fine
A Break from Tradition
This isn't just about showing off. Removing the need for holes and plastic buttons solves some of the biggest headaches in hardware design:
**The Ultimate in Hygienic Design:** In medical and industrial settings, buttons are dirt traps. A solid, seamless metal surface has no crevices for bacteria to hide in.
**Long-Lasting Devices:** Removing moving parts without losing control or functionality means no more buttons getting dirty, sticky, or worn down with use.
**The Premium Factor:** There is nothing quite like the cool touch of real steel or aluminium. Automotive and hi-fi brands can now keep that seamless "monolith" look without sacrificing smart controls like sliders or scroll wheels.
We've turned "dead" structural material into a smart interface — moving from simple buttons to full XY trackpad functionality on solid opaque surfaces.
To the laws of physics: we still respect you. We just found a way to work around you.
