In this study, okra gum polysaccharides derived from stem waste extract were utilized as a raw material for synthesizing hydrogel matrices. The polysaccharide‐rich was combined with gelatin to enhance the gelation properties of resulting hydrogels. To assess and compare self‐healing capabilities fabricated hydrogels, natural nontoxic crosslinking agent, succinic acid, introduced into formulations at different ratios (5%, 7.5%, 10% w / v ), imparting dual network structure Characterization synthesized hydrogels conducted using scanning electron microscopy (SEM), Fourier‐transform infrared spectroscopy (FTIR), differential calorimetry (DSC) analyses, providing comprehensive understanding their structural thermal properties. Furthermore, series three assays, including gel block fusion tests, electrical conductivity assessments, mechanical evaluations, employed evaluate influence acid on efficacy okra–gelatin composites. These investigations revealed promising outcomes, acid–enhanced formulation exhibiting remarkable ratio 95% an recovery rate 96.2%. Additionally, incorporating in proportions OK‐GUM‐GELSA resulted decreased swelling values. findings underscore significant potential agent enhancing polysaccharide‐based matrices, thereby paving way applications various fields, such sustainable sensors. materials can provide environmentally friendly options monitoring physiological environmental changes, while enhanced contribute more durable reliable sensors electronic applications.
