Multimodal health monitoring and theranostics based on functionalized hydrogels and artificial intelligence
Functionalized hydrogels are ideal flexible interfaces for multimodal health monitoring and integrated diagnosis-therapy systems, owing to their tissue-like mechanical properties, programmable biochemical functions, and hierarchical pores. However, practical applications are often limited by several material bottlenecks: mechanical fatigue and conductivity loss under cyclic stress, the mismatch between degradation rate and functional lifespan, and the trade-off between sensitivity and biocompatibility. To address these challenges, artificial intelligence (AI) has been applied to accelerate structural optimization and property prediction through molecular network engineering and inverse design. Meanwhile, during the collection of coupled mechanical and biochemical signals, these interfaces usually suffer from high background noise, data variability, and baseline drift. Machine learning and deep learning can process these complex datasets through noise filtering, automated feature extraction, and pattern recognition, enabling continuous monitoring and adaptive health management. This review summarizes the recent material design strategies of functionalized hydrogels, AI-driven data analysis methods, and their progress and challenges in integrated diagnosis and therapy.

Biodegradable Self-Powered Electrotherapy Patch for Integrated Smart Wound Management
Smart patches based on multimodal wearable devices enable real-time physiologic monitoring and proactive interventions to promote wound healing. Herein, we describe a biodegradable wearable electrotherapy patch (E-patch) that integrates noninvasive self-powered electrical stimulation (ES) therapy for tissue regeneration and a multiplexed electrochemical biosensor array for continuous monitoring of wound status. Custom-developed supercapacitor arrays (SCs) supply stable energy for ES, and constructed wearable biosensors enable sensitive monitoring of biomarkers in the wound exudate. As-fabricated wearable E-patches degrade harmlessly after operation, significantly reducing the environmental pollution pressure associated with flexible electronics. In vitro studies demonstrated that an applied electric field (EF) significantly promotes cell-directed alignment, which is crucial for tissue regeneration and remodeling. In vivo investigations in the Sprague-Dawley (SD) rat model illustrate that combination therapy dramatically accelerates wound healing. Overall, this work provides a promising strategy toward integrated smart wound management and future feedback-assisted wearable therapeutic systems.

A multifunctional porous interface bridging 3D architected electronics with skin
Skin-integrated flexible electronics are rapidly advancing from short-term use to continuous, long-term wear to meet the demands of health monitoring, wound healing, and skin disease treatment. While three-dimensionally (3D) architected devices offer sensing capabilities and outstanding mechanical performances, the development of a conformal interface between these 3D electronic devices and skin for long-term comfortable wear remains challenging due to their geometric complexity and mechanical fragility. Here, we introduce a multifunctional porous interface that bridges 3D flexible electronics with skin through engineered microporous networks. Such a porous design enhances elastic stretchability and electrical reliability while providing moisture permeability, thermal buffering, impact mitigation, and drug delivery capability. Stiffness reduction and localized pore-wall-shell buckling synergistically underpin the outstanding mechanical resilience under large deformations. The proposed multifunctional porous interface allows development of a 3D closed-loop wound administration patch capable of multimodal sensing and on-demand therapy, markedly accelerating scald wound healing in vivo.
