Abstract

Overview

In human body communication (HBC), the human body is utilized as a medium to transmit data between devices, which serves as an alternative to traditional wired and wireless technologies.

Function as Antenna

The human body acts as an antenna in the utilized low-frequency band, crucial for HBC technologies.

Impact of Electromagnetic Interference

Due to its antenna-like function, the human body may absorb electromagnetic waves emanating from various electronic devices and wireless services. This absorption leads to electromagnetic interference (EMI) in HBC devices, posing potential health risks.

• Study Insights: The interference signals were measured while a human subject using an HBC device was exposed to typical EMI environments at multiple locations.
• Model Development and Application: An interference model was devised from these measurements to simulate the bit-error-rate degradation, which demonstrates the potential issues in data transmission reliability in HBC devices under EMI.

Conclusion

The study provides a critical interference model that can be employed to enhance the reliability of data communication in various HBC devices amidst electromagnetic disturbances.
