Type 1 diabetes (T1D) in pediatric populations presented unique therapeutic challenges, with suboptimal glycemic control contributing to acute complications and long-term microvascular disease despite advances in insulin delivery technologies. Smart insulin patch systems represented an emerging paradigm combining glucose-responsive materials, microneedle technology, and biocompatible polymers to achieve autonomous insulin delivery mimicking physiological β-cell function without electronic components or continuous glucose monitoring integration. This narrative review critically evaluated the biochemical mechanisms, preclinical evidence, and translational potential of smart insulin patches specifically for pediatric T1D management. A comprehensive literature search of PubMed, Embase, and Web of Science databases (2015–2025) was conducted using terms including “smart insulin patch,” “glucose-responsive,” “microneedle,” “pediatric diabetes,” and “closed-loop delivery.” Principal findings demonstrated that glucose-oxidase-based, phenylboronic acid-modified, and glucose-binding protein-incorporating patches achieve rapid insulin release in hyperglycemic conditions with substantially reduced hypoglycemia risk in preclinical models. Microneedle arrays enabled painless transdermal delivery with enhanced patient acceptability, particularly relevant for pediatric populations experiencing needle anxiety and compliance challenges. However, translation to clinical practice remained constrained by limited bioresponsiveness kinetics, inadequate release dynamics for postprandial glycemic excursions, biocompatibility concerns with repeated applications, and absence of pediatric-specific clinical trials. Smart insulin patches offered promising potential for revolutionizing pediatric T1D management contingent upon optimization of responsiveness, durability, and rigorous clinical validation in younger populations.
