摘要

The skin’s extensive surface and dense mechanoreceptors make it a powerful yet underused channel for conveying complex information through touch. While wearable haptic technologies have advanced human–computer interaction, existing systems remain constrained by limited feedback diversity, localized coverage and discomfort from rigid or adhesive-based designs. Overcoming these constraints is essential for advancing somatosensory communication and immersive human–machine interfaces. Here we present a garment-compatible bistable soft-pneumatic textile interface that enables full-body, multimodal tactile feedback by integrating elastic bistable shells and soft-pneumatic textile compartments. This system generates a broad spectrum of programmable haptic cues—including pressing, vibrating, sliding and high-impact striking—with single actuators delivering up to 14 N of force and array-level control supporting distributed spatiotemporal tactile rendering. Quantitative physiological and perceptual evaluations demonstrate reliable neural activation and discrimination across multiple haptic modes. These findings establish a scalable, energy-efficient platform for immersive virtual environments, tactile communication and assistive sensory substitution, highlighting the potential of textile-based haptics for next-generation wearable somatosensory augmentation.
