Perspectives on terahertz honey bee sensing

Abstract

Overview

Terahertz (THz) technology offers precise monitoring tools for dynamic environments, shedding light on insect habitats in ways not previously possible. This study targets the environmental monitoring of European honey bees (Apis mellifera) through both direct measurements and sophisticated simulations.

Findings

• Dielectric Characterization: The dielectric properties of various honey bee body parts were measured across 1–500 GHz, generating diverse empirical data relevant to EMF exposure.
• Mockup Validation: Mockups crafted from polyamide 12 (PA12) and epoxy resin effectively substituted for real bees in scattering analyses, ensuring experimental consistency and safety.
• Advanced THz Techniques: The study leveraged radar cross-section (RCS), imaging, and spectral analyses using resonant tunneling diodes (RTDs) at 250 GHz and THz time-domain spectroscopy (THz-TDS) above 250 GHz for detailed insight.
• High-Resolution Imaging: Fine anatomical details of real and 3D-printed bees were visualized using a 450 GHz bandwidth, demonstrating the power of THz imaging for biological monitoring.
• Dosimetry & Feasibility: Computer simulations at 300 GHz assessed exposure dosimetry and examined the feasibility of non-invasive, continuous monitoring techniques using realistic bee models, directly addressing EMF safety considerations.

Conclusion

This research illustrates the significant potential of terahertz technology in monitoring bee environments. It includes explicit dosimetric assessments that emphasize possible health and safety risks linked to electromagnetic field exposure for living organisms, furthering the connection between EMF exposure and its biological impacts.
