Strain tuning is highly favored as a dynamic regulation strategy because of its simple operation and rapid response. However, achieving broadband tunability and strong low\u2010frequency absorption in strain\u2010tunable microwave absorbers remains challenging, as even slight compression can lead to significant increases in conductivity. Herein, we develop a spherical\u2010pore\u2010structured graphene aerogel (SPGA) through a microbubble\u2010templating method. The spherical\u2010pore\u00a0topology effectively suppresses strain\u2010induced percolation of conductive networks, rendering the electrical conductivity only weakly dependent on strain. SPGA achieves dynamic frequency tuning across 3.6\u201318\u00a0GHz while maintaining strong absorption under compressive strains of up to 70%. Simultaneously, it delivers enhanced low\u2010frequency absorption with an effective absorption bandwidth\u00a0of 2.56\u00a0GHz, spanning 91% of the low\u2010frequency microwave spectrum. These results demonstrate the potential of topology\u2010guided structural design for strain\u2010tunable microwave absorption and suggest a viable route for the rational design of intelligent microwave absorbers.<\/jats:p>","DOI":"10.1002\/advs.76348","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T14:08:37Z","timestamp":1782914917000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Graphene
