Abstract Microwave absorption materials (MAMs) are originally developed for military purposes, but have since evolved into versatile with promising applications in modern technologies, including household use. Despite significant progress bench‐side research over the past decade, MAMs remain limited their scope and yet to be widely adopted. This review explores history of from first‐generation coatings second‐generation functional absorbers, identifies bottlenecks hindering maturation. It also presents potential solutions such as exploring broader spatial scales, advanced characterization, introducing liquid media, utilizing novel toolbox (machine learning, ML), proximity lab end‐user. Additionally, it meticulously compelling medicine, mechanics, energy, optics, sensing, which go beyond efficiency, along current development status prospects. interdisciplinary direction differs previous primarily focused on meeting traditional requirements (i.e., thin, lightweight, wide, strong), can defined next generation smart absorbers. Ultimately, effective utilization ubiquitous electromagnetic (EM) waves, aided by third‐generation MAMs, should better aligned future expectations.
