On-device health tracking for blind football players
A skin-tight sensor bib fuses seven biosignals and runs the models on-body, so athletes who can't self-monitor get real-time health insight with no phone and no cloud.
Overview
A wearable for blind football players, where knowing an athlete's true physiological state matters more because they can't rely on visual cues. The vest fuses HR, SpO2, HRV, skin temperature, and IMU activity on-device, cleans the noise off a moving body, and runs a tiny quantized model in real time. Built with a national organization to mass-produce and distribute it.
Seven channels (HR, SpO2, HRV, skin temp, IMU) fused in real time into one physiological picture.
A denoising autoencoder plus adaptive Kalman filter cut motion artifact 43% on a sprinting, colliding athlete.
A pruned, INT8-quantized model runs in under 8ms on a microcontroller, under a milliwatt budget, no cloud.
Partnered with a national organization to mass-produce and distribute to 500+ blind football players.
