The　integration　of　softness　and　rigidity　underpins　the　concept　of　variable　stiffness,　leveraging　the　distinct　advantages　of　both　properties.　Inspired　by　this　concept,　this　paper　introduces　a　stiffness-switchable　composite　structure　achieved　through　laminar　jamming　enabled　by　the　inherent　dry　adhesion　force　of　microwedge　adhesives.　This　mechanism　allows　for　a　reversible　transition　between　high　flexibility　and　pronounced　rigidity,　achieving　a　remarkable　stiffness　ratio　of　75,　with　easier　implementation　and　enhanced　functionality.　Comprehensive　modeling　and　experimentation　are　conducted　to　reveal　intricate　aspects　of　the　structure＇s　mechanical　properties,　such　as　interlayer　behavior　and　failure　processes.　This　paper　also　outlines　two　potential　applications　for　this　multifunctional　structure:　a　robotic　gripper　with　dual　modes　of　rigid　pinch　and　compliant　adhesion,　and　an　integrated　multifunctional　sensing　setup.　The　proposed　structure　might　broaden　the　scope　of　dry　adhesives　and　laminar　jamming　structures,　suggesting　new　possibilities　for　future　research　and　development.
