KeiFit: wearable EMG sensor.

A wrist-worn surface-EMG sensor with on-device continuous-time inference. Turns raw muscle signals into gesture and intent estimates locally, with no cloud handoff.

What it does

KeiFit reads surface electromyography from the wrist and runs a compact continuous-time neural network on the embedded MCU to produce gesture and intent estimates. The same continuous-time machinery powers the KeiT0 prosthetic upstream.

Why it matters

The wrist is the cleanest place for EMG outside a clinical setup. KeiFit makes that signal usable as an HCI input — and as a bridge to medical-grade applications running on the same model family.
