Smart wireless power transfer — opportunities and challenges

Popularization of wireless power transfer (WPT) has promoted the multi-disciplinary explorations and integration. It gradually incubates numerous attractive solutions for industrial, domestic and medical scenarios. Therefore, a series of smart WPT emerges, and these state-of-the-arts will bring a great impact on the modern technology and human society. This review investigates and discusses the opportunities and challenges of the smart WPT, especially in the areas of wireless energy modulation, conversion and intellectualization. The key is to reveal the methodologies, approaches and foresights for the emerging technologies of the smart WPT. As one of the most promising development trends, the smart WPT will embrace the information-energy internet and construct the wireless energy router and wireless energy internet that support the wireless energy trading for peers, communities and energy internets.
