Human body motions can have a significant impact on on-body electromagnetic (EM) wave propagations and affect wireless body area network (WBAN) applications. To help understand the body motion effects, an arm-swinging phantom model of the human upper body is developed in both measurement and simulation. The phantom model performance is compared to human volunteer results and shows similar time-varying behaviors. Wireless Body Area Networks (WBANs) are increasingly being used for real-time monitoring of physiological signals in patients. The ESP-WROOM-32 module is a popular Wi-Fi and Bluetooth module that can be used for developing WBAN systems. This paper presents a design and implementation of a WBAN system using the ESP-WROOM-32 module. The system includes various physiological sensors, power source, antennas, display, and software for data processing. The ESP-WROOM-32 module provides built-in Wi-Fi and Bluetooth connectivity, making it an efficient and reliable choice for developing WBAN systems. The paper also discusses the challenges and opportunities associated with the development of ESP-WROOM-32-based WBAN systems. The proposed system can be used for remote monitoring of patients in healthcare settings, sports performance monitoring, and other applications. Overall, this research demonstrates the potential of using the ESP-WROOM-32 module for developing efficient and reliable WBAN systems.
