本文综述了近场电动无线电能传输（EWPT）的最新进展，该技术依靠发射机产生的时变磁场来激励接收机中永磁体的机械运动。由磁体吸收的机械能然后经由一个或多个换能机制（最常见的是法拉第感应）转换成电能。EWPT与其他无线功率策略进行了比较，并提供了功率传输的理论上界。
This article summarizes recent advancements in near-field electrodynamic wireless power transmission (EWPT), which relies on a time-varying magnetic field produced by a transmitter to excite the mechanical motion of permanent magnet in the receiver. The mechanical energy absorbed by the magnet is then converted into electrical energy via one or more transduction mechanisms, most commonly Faraday induction. EWPT is compared against other wireless power strategies, and theoretical upper bounds of power transmission are provided.
