PhysTech 2026 hackathon — NeckQuest: a Holter monitor for neck tension
NeckQuest is an open-source ESP32-S3 wearable that measures the electrical activity of the left upper trapezius
and classifies the muscle state as relaxed or tense in real time. The video covers the problem, the hardware, the
EMG pipeline, the personal SVM classifier, and the Holter recording workflow.
