Can I read torque specs with greasy hands under the lift?

Yes. Bump Pad 1 at the elbow so your knuckles never touch the sleeve, and the matrix shows LUG 100 FT-LB or CALIPER 35 FT-LB.

Can I switch between FT-LB and N·m?

Double-tap Pad 2 to toggle units, so 100 FT-LB also reads as roughly 135 N·m.

What if oil soaks into the fabric?

Slide the sealed electronics out of the inner pocket and hand-wash the matte-black sleeve in cold water; the conductive-fabric pads keep working.

Why Phone, Watch, and Paper Spec Sheets Fail Under a Lift

Glare and grease: Shop glare washes out a phone screen, and paper spec sheets tear, blow away, or soak through with oil.
The answer arrives on your body: A few inches of matte-black fabric becomes a glanceable, tap-through control surface where your hands already are.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
