Electro-Quasistatic Human-Structure Coupling for Human Presence Detection and Secure Data Offloading.

Area of Science:

• Electrical Engineering
• Biomedical Engineering
• Wireless Communication

Background:

• Human Body Communication (HBC) offers energy-efficient and secure data exchange.
• Exploration of communication between the human body and surrounding objects is increasing.
• Need for non-contact sensing and secure data offloading is critical.

Purpose of the Study:

• Propose Inter-Structure communication guided by the human body.
• Analyze Structure-Human-Structure Interaction (SHSI) in the Electro-Quasistatic (EQS) regime.
• Investigate non-contact sensing and secure data offloading.

Main Methods:

• Utilized Finite Element Method (FEM) for simulations.
• Studied positional variations of structures relative to the body and ground.
• Validated simulation trends through experimental analysis.

Main Results:

• Human presence between structures boosts received voltage by ~8 dB.
• A grounded receiver further increases signal level by ~18 dB.
• Demonstrated low loss and enhanced physical security in EQS signal transmission.

Conclusions:

• SHSI analysis in the EQS regime enhances HBC capabilities.
• Non-contact sensing and secure data offloading are feasible with this approach.
• The proposed method provides a foundation for advanced human-centric communication systems.
