In the current digital era, intelligent wearable devices have become an indispensable part of people's lives and work. Through their unique design and equipped hardware and software technologies, they enable users to quickly and efficiently acquire and process personal data, thus achieving better life and work efficiency. In these devices, wireless sensing technology plays a very important role. By combining wireless networks, sensing technology, and human-computer interaction, these devices provide rich functionality and a convenient user experience. However, the current wearable intelligent devices are lacking in specific applications, and there is a risk of data privacy leakage. Through control variable method, comparative method and experimental method, the experimental part conducted research and exploration on counting accuracy, distribution range and accuracy of heart rate measurement under different exercise states, data transmission speed under different wireless connection methods, and performance testing of wearable intelligent devices (high-temperature environment performance; low-temperature environment performance; waterproof level indicators; battery life). After testing, the overall step accuracy of the product designed in this article was above 96.5 %, and the overall measurement accuracy of heart rate under various exercise states was above 92 %. The data transmission speed is fast and stable, and the other evaluations are relatively excellent. Wearable intelligent devices based on wireless networks have broad application prospects in improving quality of life, health management, and intelligent services. With the advancement of technology and the continuous changes in user needs, wearable devices can continue to develop and bring more convenience and intelligent experiences to people's daily lives. |
