A compact wearable device with built-in biometric sensors that tracks your health around the clock. It measures heart rate, SpO2, and temperature, and sends the data to the cloud for analysis.
PPG, accelerometer, temperature, SpO2, and galvanic skin response sensors on flexible PCB
Nordic nRF52840 SoC with BLE 5.0 and on-device signal filtering and feature extraction
Encrypted BLE data transfer to mobile app with automatic cloud backup and analysis
Flutter mobile app with real-time vitals, trend graphs, and personalized health insights
A photoplethysmography sensor with adaptive sampling gives accurate BPM readings during rest and exercise.
Dual-wavelength SpO2 sensor with medical-grade accuracy for continuous oxygen saturation tracking.
Skin temperature sensor with 0.1C resolution for circadian rhythm monitoring and fever detection alerts.
6-axis IMU with ML-based activity classification detecting walking, running, sleeping, and sedentary states.
Smart power management and dynamic sensor duty cycling give the device 72 hours of battery life on a single charge.
End-to-end encrypted data transmission with on-device anonymization and HIPAA-compliant cloud storage.
Evaluated PPG, IMU, and temperature sensors for accuracy, power consumption, and form factor compatibility.
Flexible 4-layer PCB design with component placement optimized for a wrist-worn enclosure under 12mm thick.
nRF52840 firmware with real-time signal conditioning, heart rate extraction, and BLE GATT service implementation.
Flutter cross-platform app with real-time BLE data streaming, trend visualization, and health insight engine.
Comparison testing against medical-grade devices for heart rate, SpO2, and temperature measurement accuracy.
From biometric sensors to mobile health apps, our team builds wearables that pair medical-grade accuracy with a design people actually want to wear.
