Mobile AIGC technology automates information creation at mobile edge networks, benefiting personalized healthcare through HDT applications. This article proposes a system architecture for mobile AIGC-driven HDT, addressing design requirements and challenges. Use cases in surgery planning and personalized medication are presented, along with evidence of effectiveness in a virtual physical therapy teaching platform. Open issues and future directions are discussed.

The article discusses Tactile Internet (TI) and its role in enabling haptic human-machine interactions. It introduces the concept of human digital twin (HDT) and proposes edge computing empowered TI (ECoTI) for HDT. It presents the system architecture, design considerations, and challenges of ECoTI, along with implementation guidelines. An experimental study demonstrates ECoTI’s effectiveness in physical therapy. The article concludes by discussing open issues and future research directions.

This paper introduces a blockchain-enabled data sharing framework for latency-sensitive applications. It includes a parallel validation-based consensus approach with reputation enhancement and a priority-based block appending process. The framework improves performance while maintaining security and decentralization. Simulation results demonstrate higher throughput, lower latency, and acceptable security levels.
