Abstract
Laminated magnetoelectric(ME)energy harvesters,with the advantages of miniaturization,flexibil-ity,and diversified functions,have wide application prospects in self-powered monitoring of low-power devices,such as implanted medicine,Internet of Things(IoT),and micro-electromechanical systems(MEMS).The latest research progress in harvesters is reviewed,introducing their magneto-mechano-electric(MME)coupled energy con-version mechanisms.The types and structural features of various high-and low-frequency magnetic energy harvest-ers and low-frequency hybrid energy harvesters are examined,and their performances are comprehensively compared and analyzed.The potential advantages of high-frequency magnetic energy harvesters in wirelessly powered medical diagnosis and treatment of implanted devices are highlighted.Further,the significant advantages of low-frequency harvesters in self-powered sensing and monitoring of current-carrying IoT devices are indicated.Finally,existing problems and future development directions for harvesting technology are summarized.
