An Electrical Switch‐Driven Flexible Electromagnetic Absorber

The development of a thin, tunable, and high‐performance flexible electromagnetic (EM) absorbing device that aims to solve signal interference or EM pollution is highly desirable but remains a great challenge. Herein, demonstrated is a flexible electrical‐driven device constructed by an insulated organic‐polymer substrate, carrier transmission layer, and core–shell structured absorber, enabling a narrow and tunable effective absorption region (...
