Stretchable microwave absorbers (SMAs) are vital for flexible electronics. Traditional SMAs display unstable tensile properties resulting from inconsistencies between the constrained conductive layer and dielectric layer. This study introduces an organohydrogel-based stretchable absorber (OSMA) that incorporates organohydrogel within island-bridge structure. Leveraging standing wave field concentration effects, along with strain dissipation, OMSA achieves 90% absorption in 5–18 GHz range maintains stable broadband under a 30% uniaxial stretch, exhibiting tunable angular performance transverse electric/magnetic (TE/TM) polarization. approach offers versatile, customizable, cost-effective solution SMAs.
