Raw data for Fully stretchable moisture-electric generators with peak milliamp-scale output via conformationally adaptive ionic hydrogels for wearables jiangtao li (24912841) Other physical sciences not elsewhere classified moisture-electric power generators <p dir="ltr">Moisture-electric generators (MEGs) that harvest ambient or physiological moisture offer a promising route to self-powered wearable and deformable electronics. However, their practical applications are hindered by insufficient moisture-responsive output and unstable performance under strain. Here, we report a fully stretchable MEG with peak milliamp-scale output for self-powered epidermal sensing, enabled by an in situ formed, conformationally adaptive hygroscopic ionic hydrogel adhesively integrated between two stretchable asymmetric-porosity styrene–ethylene–butylene–styrene (SEBS) composite electrodes. The hydrogel encodes charge-selective pathways that drive quasi-two-dimensional, oppositely directed counter-ion migration, enabling rapid ion separation and high ionic conductivity (8.1 S m-1). Its reversible helix–coil transitions preserve ion transport under strain by dissipating strain energy across multiple scales. Coupled with SEBS composite electrodes that facilitate continuous moisture delivery and reliable electrical contact during stretching, the device achieves a peak current density of 1.1 mA cm-2 upon moisture activation, while remaining fully stretchable up to 400% strain and stable at 200% strain over 1000 cycles with minimal output degradation. We show its use as a self-powered, deep-learning-assisted skin-hydration sensing platform, achieving 98% classification accuracy during extended on-body operation with smartphone feedback. This approach to designing deformation-tolerant MEGs will enable next-generation self-powered, skin-conformal healthcare electronics.</p> 2026-09-15T05:55:13Z Dataset Dataset 10.6084/m9.figshare.33772234.v1 https://figshare.com/articles/dataset/Raw_data_for_Fully_stretchable_moisture-electric_generators_with_peak_milliamp-scale_output_via_conformationally_adaptive_ionic_hydrogels_for_wearables/33772234 CC BY 4.0
