Improving accuracy, BLE reliability, and battery performance across the smart earring, charging case, and companion app.
Background
A women’s health wearable company was building smart earrings for continuous physiological monitoring with a companion mobile app. As they moved from prototype to commercialization, they needed better measurement consistency, stable BLE syncing across the earring and charging case, and stronger battery performance in a compact form factor.
Outcomes
- Improved HRV and SpO₂ accuracy to within 1% versus a CE-approved reference device
- Stabilized BLE communication and synchronization across the smart earring, charging case, and companion app
- Achieved 24-hour battery backup without increasing device size
- Delivered an end-to-end MVP including hardware, firmware, and Android and iOS app integration with historical visualization and device health monitoring
