Health-Care Based on Near Field Inter-Body Coupling Communication: Modeling and Analysis of Characteristics

The Internet of Bodies (IoB) enables short-range, low-power communication for implantable medical devices, presenting significant advantages for leadless pacemakers and defibrillators. Near Field Inter-Body Coupling Communication (NF-IBCC) emerges as a promising approach, offering enhanced data security and reduced power consumption compared to traditional radio frequency (RF) methods. However, a comprehensive understanding of its channel model remains elusive. This study introduces a circuit-based channel model for NF-IBCC, validated through experimental analysis. The model characterizes key factors influencing NF-IBCC, including distance, posture, angle, and height, laying a theoretical foundation for its application in IoB and related healthcare applications.
