Wireless vital-sign monitoring

Non-invasive monitoring of ECG, blood pressure, SpO₂, and continuous glucose across patch and ring form factors — including a 5-lead ECG patch with cloud publishing and offline logging, and AI-based cuffless blood-pressure estimation running on a coin cell.

The form factor set the budget for everything: radio duty cycle, sensor sampling rate, and signal-processing load were all traded off against a coin-cell power envelope, while the firmware kept buffering locally so a dropped connection never meant lost data.
