The rapid advancement of 5G communication has propelled society into the intelligent era. Compared with the previous 4G communication, the 5G communication system has ten times higher emission powder, nevertheless, the energy usage during electromagnetic (EM) signal transmission is only half that of the 4G system. As a result, high density of EM energy is radiated into the air, resulting in severe EM pollution that not only endangers human health but also compromises information security. In addition to EM pollution, the lack of high-efficiency usage of EM energy has been another ignored issue for currently energy crisis. This perspective puts forward strategies to utilize the EM energy, key challenges that should be overcome, as well as insights to overcome these barriers to realize highly efficient EM harvester.

5G通信技术的飞速发展推动社会进入了智能时代。与4G通信相比，5G通信系统的发射功率提高了10倍，电磁信号传输过程中的能量消耗减少了一半。然而随之带来的问题是：高密度的电磁能量辐射到空气中造成严重的电磁污染，这不仅会危害人类健康，还会危及信息安全。除电磁污染之外，电磁能量缺乏高效利用一直是当前能源危机中另一个被忽视的问题。这篇前瞻性论述提出了高效利用电磁能量的策略、目前需克服的关键挑战，以及关于如何实现高效电磁能量收集的一些见解。
