The remarkable flexibility and heightened sensitivity of flexible sensors have drawn significant attention, setting them apart from traditional sensor technology. Within this domain, hydrogels—3D crosslinked networks hydrophilic polymers—emerge as a leading material for the new generation sensors, thanks to their unique properties. These include structural versatility, which imparts traits like adhesiveness self-healing capabilities. Traditional templating-based methods fall short tailor-made applications in crafting sensors. In contrast, 3D printing technology stands out with its superior fabrication precision, cost-effectiveness, satisfactory production efficiency, making it more suitable approach than strategies. This review spotlights latest hydrogel-based developed through printing. It begins by categorizing hydrogels outlining various 3D-printing techniques. then focuses on range sensors—including those strain, pressure, pH, temperature, biosensors—detailing applications. Furthermore, explores sensing mechanisms concludes an analysis existing challenges prospects future research breakthroughs field.
