Abstract
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通信技術(shù)的飛速發(fā)展推動社會進入了智能時代。與4G通信相比，5G通信系統(tǒng)的發(fā)射功率提高了10倍，電磁信號傳輸過程中的能量消耗減少了一半。然而隨之帶來的問題是：高密度的電磁能量輻射到空氣中造成嚴重的電磁污染，這不僅會危害人類健康，還會危及信息安全。除電磁污染之外，電磁能量缺乏高效利用一直是當(dāng)前能源危機中另一個被忽視的問題。這篇前瞻性論述提出了高效利用電磁能量的策略、目前需克服的關(guān)鍵挑戰(zhàn)，以及關(guān)于如何實現(xiàn)高效電磁能量收集的一些見解。
本文亮點
1.提出了兩種利用電磁能量的方式：（1）直接將電磁能轉(zhuǎn)換為電能；（2）首先將電磁能量轉(zhuǎn)化為其他形式的能量，再轉(zhuǎn)換為電能。
2. 指出了在利用電磁能量過程中存在的問題與挑戰(zhàn)，提出了可能的解決方法，并對該領(lǐng)域未來研究方向進行了前瞻。
