TK9 Smart Ring

I. Product Overview
The smart ring is a wearable device that integrates cutting-edge micro-sensors and algorithms. It seamlessly blends the decorative qualities of a traditional ring with the power of modern technology. Its core features include seamless wear, long battery life, and precise monitoring, designed to be your 24/7 personal health and lifestyle manager.
It doesn't require frequent interaction like a phone, nor is it burdensome like a watch. Instead, it silently records your body data and protects your health in a lighter, more durable way.

II. Core Features and Highlights
1. Comprehensive Health Monitoring
· Accurate Blood Oxygen Saturation (SpO2) Monitoring: It specifically monitors blood oxygen levels during sleep, providing critical data for assessing sleep quality and respiratory health.
· 24/7 Heart Rate Monitoring: Continuously tracks heart rate changes and provides instant alerts for abnormal heart rates, helping you identify heart health risks.
· Temperature Trend Monitoring: It records subtle changes in basal body temperature, which can be used to assess stress levels and women's health cycles (such as ovulation). · HRV (Heart Rate Variability) Analysis: Provides in-depth analysis of the state of the autonomic nervous system, a key indicator of body stress, recovery, and overall health.

2. Professional Sleep Analysis
· Multi-dimensional Sleep Monitoring: Automatically identifies sleep onset and wake-up times, accurately analyzing the duration and distribution of light sleep, deep sleep, and REM (rapid eye movement) sleep stages.
· Sleep Quality Score: Generates a daily sleep report and score based on heart rate, blood oxygen, body movement data, and other data, and provides personalized improvement suggestions.
· Sleep Environment Monitoring: Select models support monitoring of ambient temperature and humidity during sleep to help optimize the sleeping environment.

3. Efficient Exercise Tracking
· Multi-Mode Exercise Recognition: Automatically or manually records various exercise modes, including walking, running, cycling, and swimming (waterproof support required), and calculates calorie consumption.

· Exercise Performance Evaluation: Quantifies your training effectiveness through professional metrics such as maximum oxygen uptake (VO₂ Max) and excess post-exercise oxygen consumption (EPOC), helping you improve scientifically.

4. Excellent Product Design
· Comfortable Wear: Made of lightweight materials (such as titanium alloy and ceramic) and ergonomically designed, the wearer is comfortable and effortless, even at night.
· Long Battery Life: A miniaturized battery and low-power chip design deliver 5-7 days of extended battery life, eliminating the need for daily charging.
· Waterproof and Dustproof: Typically IP68 or higher, these devices are water-resistant, resistant to sweat, rain, and everyday splashes, making them suitable for use during exercise and washing.
