Electromagnetic (EM) absorbers drive the development of EM technology and advanced EM equipment. The utilization of EM energy conversion of the EM absorber to design a variety of devices is attractive and promising, especially in personal protection and healthcare. In this review article, wearable EM materials are reviewed, ranging from design strategies, EM response mechanism, EM performance improvement, to the construction of smart EM devices. For EM response mechanism, the relaxation and charge transport associated with radiation energy conversion are dissected. For wearable EM devices, two main functions are highlighted, including EM sensors to replace of human senses, as well as EM absorbers to block transmission radiation. Furthermore, the current issues and potential opportunities of the wearable EM devices are pointed out, and new directions for future prospects are proposed.
