Over the past decade, research on wireless power transfer has led to the development of several commercial applications, such as wireless charging of mobile devices and electric toothbrushes, as well as wireless powering of radio-frequency identification (RFID) tags. However, these applications are restricted by limitations on the distance and efficiency of current wireless power transfer technology.
In a new study published in EPL, scientists at Tongji University in Shanghai, China, have experimentally demonstrated a way to improve the efficiency of wireless power transfer by using magnetic metamaterials.
