Bio-aware Terahertz Communication for 6G: Exploring Health-conscious Design in Ultra-fast Networks

Abstract

As Sixth-Generation (6G) wireless networks advance Toward Harnessing Terahertz (THz) frequencies—ranging roughly from 0.1 to 10 THz—to achieve unprecedented data rates, ultra-low latency, and massive connectivity, growing attention is being directed toward the potential biological implications of prolonged THz exposure. This study introduces the emerging paradigm of bio-aware terahertz communication, which emphasizes the integration of biological safety and health-conscious design principles into the core of 6G network planning, architecture, and deployment. Drawing from recent biomedical research, the study reviews how THz radiation interacts with human skin, ocular tissues, and even plant systems, highlighting both thermal and non-thermal effects observed at cellular and molecular levels. Building on these insights, the study proposes engineering guidelines for safe antenna design, adaptive beamforming strategies to minimize unnecessary exposure, and spatial deployment models that respect exposure thresholds. Additionally, it discusses experimental and simulation-based frameworks for evaluating and predicting biological impacts under realistic operational conditions. By merging communication system optimization with biomedical safety awareness, the proposed framework aims to establish a balanced ecosystem where technological progress does not compromise human and environmental health. Ultimately, bio-aware THz communication envisions a sustainable 6G future—one that ensures ultra-fast, reliable connectivity while maintaining scientific and ethical responsibility toward biological well-being.
