Sensor bands, compared
Strip the screen off a smartwatch and what remains is the band: a strap of sensors that trades apps and notifications for battery life and better data. WHOOP built a business on it; a new wave adds AI voice capture and even neural input — bands that read the muscle signals in your wrist.
The index lists mainstream watches only where they push the frontier of on-body computing; the interesting action here is in what screenless hardware can sense that a watch can't afford to.

Common questions
How is a sensor band different from a smartwatch?
Strip the screen off a smartwatch and what remains is the band: a strap of sensors that trades apps and notifications for weeks of battery and richer data. WHOOP built a business on it; newer bands add AI voice capture and even neural input.
What is a neural input band?
A band that reads the electrical activity of the muscles in your wrist (surface EMG) and turns tiny finger movements into input — no camera, no controller. Meta's Neural Band, which drives the Ray-Ban Display glasses, brought the idea to consumers.
