Fitness Trackers Technology

Fitness trackers are wearable devices designed to monitor and record various health and activity metrics. They use sensors, wireless connectivity, and software to help individuals track physical activities, fitness goals, and overall wellness. These devices have evolved from simple pedometers to advanced health-monitoring systems.

Key Components and Features

1. Sensors

   • Accelerometer & Gyroscope: Measure steps, movement, and orientation.

   • Optical Heart Rate Monitor (PPG): Tracks pulse using light-based sensors.

   • GPS Module: Records routes, distance, and speed.

   • SpO₂ Sensor: Monitors blood oxygen levels.

   • ECG Sensors: Provide electrocardiogram readings for heart health.

   • Skin Temperature & EDA Sensors: Track stress and body temperature changes.

2. Connectivity

   • Bluetooth / Wi-Fi: Syncs data with smartphones or cloud apps.

   • NFC: Enables contactless payments in some devices.

3. Software & Analytics

   • Mobile apps and cloud dashboards analyze activity, sleep patterns, calories burned, and workout progress.

   • AI-driven insights for personalized health recommendations.

4. User Interface

   • OLED/AMOLED touchscreens for interaction.

   • Haptic feedback and notifications.
