Wearable Devices

Overview

DevBriX supports wearable concepts from discovery to EVT, optimization, and validation, bridging the gap between product idea and functional prototype for market testing.

Highlights

• Smartwatch, smart ring, and fitness/sleep band experience
• 300+ hardware and firmware projects delivered
• Miniaturization, battery optimization, and BLE stability
• Concept-to-prototype process in 6-10 weeks

Challenges

• Make compact devices without compromising performance.
• Capture accurate wellness data such as heart rate, SpO2, skin temperature, motion, and sleep patterns.
• Maintain reliable BLE sync for a consistent user experience.
• Extend battery life through deep sleep, PMICs, and power profiling.

Solutions

• Use Nordic nRF52/nRF53, Ambiq Apollo, ESP32, or STM32 depending on performance and power needs.
• Integrate PPG, skin-temperature sensors, IMU, displays, haptics, tuned antennas, and mobile demo apps.
• Apply high-density PCB routing and flex PCB design for rings and bands.
• Support DFU over BLE, sensor fusion, and power profiling for commercial scale-up readiness.

Features

• Smartwatch prototypes
• Ultra-miniaturized smart rings
• Fitness and sleep bands
• iOS/Android demo apps
• BLE OTA updates

Key Results
