Integrating Metamaterial Antenna Node and LiFi for Privacy Preserving Intelligent COVID-19 Hospital Patient...

Area of Science:

• Optoelectronics and Sensor Technology
• Quantum Cryptography
• Biomedical Engineering

Background:

• Existing hospital networks face challenges with capacity, security, and electromagnetic interference (EMI).
• Effective COVID-19 surveillance requires high-speed data transmission and integrated sensing capabilities.
• Light Fidelity (LiFi) offers a secure, high-capacity alternative to traditional wireless technologies.

Purpose of the Study:

• To propose an integrated Light Fidelity (LiFi) system for simultaneous communication and COVID-19 surveillance in hospitals.
• To enhance network security and data transmission capacity using quantum cryptography principles.
• To develop integrated sensors for real-time monitoring of critical patient parameters and environmental conditions.

Main Methods:

• Implementation of a dual-mode LiFi network supporting communication and surveillance.
• Utilization of a Mach-Zehnder interferometer (MZI) embedded metamaterial antenna with silver bars and phase modulators.
• Application of a dark soliton entangled source for secure quantum cryptography-based data transmission.
• Generation of whispering gallery modes (WGMs) for uplink and downlink nodes.
• Integration of plasmonic antennas as temperature and electric force sensors.

Main Results:

• Achieved high-capacity data transmission (40 Pbit/s) with EMI immunity and enhanced security.
• Demonstrated LiFi system's capability for real-time temperature and electric force sensing.
• Optimized plasma force sensitivity at 0.16 N kg⁻¹ mW⁻¹ and temperature sensitivity at 0.05 rads⁻¹ °C⁻¹.
• Obtained center frequencies of 191.48 THz (uplink) and 199.41 THz (downlink).

Conclusions:

• The proposed integrated sensor circuits within a LiFi network represent a novel approach for hospital COVID-19 surveillance.
• The system enables critical patient monitoring and alert generation through a fuzzy-based system.
• This LiFi-based surveillance offers a secure, high-capacity solution for managing infectious diseases in healthcare settings.
