Advanced approaches to decoupled sensory signal monitoring in human interface systems

Highlights This review introduces the most recent advances in decoupling techniques for artificial sensory systems, emphasizing the design of sensing materials using micro/nanostructured materials, 3D sensory system architectures, and AI-based signal decoupling methods. Stress engineering of micro/nanostructures effectively reduces interference between various mechanical stimuli, while the combination of spatiotemporal information from 3D integrated sensory systems and AI-based signal processing allows simultaneous monitoring of multimodal sensory signals without cross-interference. Decoupled sensory signal monitoring systems have been applied in fields such as robotics, wearable and implantable health monitoring, enabling the development of artificial sensory systems with human-like capabilities and advanced functionality.
