Physical Components
The smart bracelet’s chassis is built from a corrosion‑resistant aluminum alloy, offering a sleek, lightweight feel while maintaining structural integrity. The front panel hosts a 1.2‑inch OLED display, protected by a sapphire‑grade glass layer that resists scratches and water ingress up to 5ATM. Beneath the display, a flexible silicone band is available in three sizes (S, M, L) and finishes (matte, gloss, textured) to accommodate various wrist sizes and style preferences. The band’s inner lining is hypoallergenic, ensuring comfort for extended wear. At the rear, a 300‑mAh lithium‑ion polymer battery powers the device, delivering up to seven days of continuous use on a single charge under typical activity monitoring conditions. The battery is sealed within a proprietary enclosure that prevents moisture and dust from penetrating the internal circuitry. The main logic board is a custom System‑on‑Chip (SoC) that integrates a dual‑core ARM Cortex‑M4 processor, 256 KB of SRAM, and 1 MB of flash memory, enabling efficient data handling and low power consumption. The sensor suite includes a 3‑axis accelerometer, a 3‑axis gyroscope, a photoplethysmography (PPG) module for heart‑rate detection, and a temperature sensor for ambient and skin temperature readings. All sensors are calibrated during the factory test cycle and are accessible via the companion mobile app for advanced users, allowing custom thresholds and data export. The enclosure also houses a small inductive charging coil that aligns with the charging dock’s magnetic field, enabling wireless charging at 5 W, and a USB‑C powered dock that can be used with any standard USB‑C cable. The device’s firmware is modular, allowing over‑the‑air (OTA) updates that add new features or improve sensor accuracy without requiring a physical reset, ensuring longevity. Overall dimensions are 45 mm in length, 18 mm in width, and 3.5 mm in thickness, making it discreet enough for both casual wear and formal occasions, while the combination of durable materials, precise sensors, and efficient power management makes it a reliable companion for daily health and connectivity needs.
Battery and Charging
The smart bracelet’s power core is a 300‑mAh lithium‑ion polymer cell, engineered for both durability and safety. In typical use—continuous activity tracking, heart‑rate monitoring, and occasional notification alerts—the device delivers up to seven days of operation on a single charge. The battery is sealed in a proprietary enclosure that protects against moisture, dust, and mechanical shock, ensuring consistent performance even in demanding environments.
Charging is achieved via two convenient methods. First, the built‑in inductive charging coil aligns with the dock’s magnetic field, delivering 5 W wirelessly; a full charge takes about 90 minutes. Second, the device supports USB‑C charging via a cable, letting users charge from a power bank or laptop.
The firmware monitors battery health and reports capacity percentage to the companion app. When the battery level falls below 20 %, the app notifies the user and suggests a charging session. The device also includes a low‑power mode that reduces sensor sampling frequency and disables non‑essential functions, extending battery life during periods of inactivity.
Safety features include over‑charge protection, reverse‑polarity detection, and temperature monitoring. The battery management system shuts down power if the temperature exceeds 60 °C or if the voltage drops below 2.5 V, preventing damage and ensuring user safety. Users are advised to keep the charging dock in a dry location and avoid exposing the bracelet to extreme temperatures during charging.
Battery lasts up to 7 days. The battery’s 300‑mAh capacity balances size and endurance, suitable for daily wear.!!!
Sensor Types
The bracelet houses an optical photoplethysmography (PPG) sensor that tracks heart rate and SpO₂ using dual‑wavelength LEDs. A 3‑axis accelerometer records steps, activity intensity, and sleep stages, while a 3‑axis gyroscope distinguishes walking, running, and cycling. An ambient light sensor adjusts display brightness, and a temperature sensor monitors skin temperature for metabolic calculations.
All sensors connect via low‑power I²C to the main MCU, which applies filtering and adaptive algorithms to suppress motion artefacts. Firmware synchronizes data with the companion app every 5 seconds, providing real‑time feedback on heart rate, steps, and sleep quality.
Battery life of up to seven days is achieved by duty‑cycling sensors during inactivity. Users can modify sampling rates in the app to balance accuracy with power consumption.
Calibration runs automatically at first boot and can be manually triggered from the app. The PPG sensor calibrates against ambient light, while the accelerometer sets its zero‑g offset. Temperature compensation adjusts SpO₂ calculations for skin temperature variations. Calibration data is stored in memory and refreshed 30 days dailyafter a firmware update.
The firmware includes a safety watchdog that monitors sensor health and resets the MCU if anomalies occur. Users are notified if battery temperature exceeds 45 °C or PPG signal quality falls below 70 %. These safeguards protect hardware and data integrity.
