Analysis of the Design of Wearable Wireless Biosensors

Abstract

With the increasing health awareness and diversification of lifestyle, wearable biosensor systems have gradually become an effective tool for monitoring individual physiological parameters. This study introduces an innovative design to address this need, which aims to monitor important physiological indicators such as heart rate, body temperature and exercise status. The system integrates a heart rate sensor (MAX30101), a body temperature sensor (DS18B20), an acceleration sensor (MPU6050), a microcontroller (ESP32) and a Bluetooth low energy module (HC-06), and is powered by a rechargeable lithium battery (18650 battery). This study adopted a system design and hardware development approach, focusing on sensor performance optimization, power consumption control. The hardware connection method of the system is described in detail, and the experimental verification is carried out. Based on the experiments, a wearable biosensor system that can accurately monitor the user's heart rate, body temperature and motion state has been successfully designed. The low-power design of the system ensures prolonged wear with potential medical, sports health and quality of life monitoring applications. These results provide a powerful tool for individualized health management, providing users with real-time knowledge of their physiological state, offering a useful reference and enlightenment for the development and application of wearable biosensor technology.
