• Filtering + noise reduction
• Calibration logic
• BLE GATT services
• Power management

---

4. Hardware Architecture

• Sensor placement
• PCB block diagram
• Power routing
• BLE antenna considerations

---

5. Ergonomic Integration

• How the electronics fit into the mouthpiece
• Comfort + safety considerations
• Material constraints
• BLE antenna considerations
