Ultra-slim smart healthband
A compact wearable combining biometric sensors, Bluetooth connectivity, gesture input, and haptic feedback.
The project
Bring sensing, feedback, charging, and wireless communication into a comfortable wrist-worn enclosure.
Product highlights
- Nordic nRF52840 platform with BLE connectivity.
- Biometric sensor integration, gesture input, and haptic alerts.
- Low-power firmware architecture and over-the-air update support.
Connected application
A companion mobile prototype demonstrates Bluetooth communication, sensor readings, device status, and alert notifications.
How we approached it
For a battery-powered Bluetooth product like the Ultra-slim smart healthband, the power budget shapes every decision. We plan how often the radio wakes, which sensors sample and how fast, and which sleep states the nRF52840, BLE hardware can use between events.
The Bluetooth interface is designed together with the companion app: which data is streamed, which is read on demand, and how settings and alerts flow back to the device. Over-the-air updates are planned from the first build so field units can be fixed without a cable. See our nRF52 vs ESP32 guide for the platform trade-offs.
