Abstract: With the ability to assist and greatly improve the spectrum efficiency of wireless information transmission (WIT) and wireless power transfer (WPT), intelligent reflecting surface (IRS) is envisioned as a key technology for future 6G communications. A comprehensive overview of the domestic and international research status of IRS-assisted WIT and WPT is proposed. First, the research on IRS-assisted WIT is summarized and analyzed, which shows that IRS plays an essential role in improving the performance of various WIT systems. Second, the research on IRS-assisted WPT is discussed, which reveals the great potential of the IRS in enhancing energy transfer efficiency. Then, the research on IRS-assisted simultaneous wireless information and power transfer (SWIPT) is emphatically described, and six future research directions of IRS-assisted SWIPT are prospected, including physical layer security, unmanned aerial vehicle (UAV) communication, multi-IRS cooperative assistance, and so on.  
Keywords: IRS; WIT; WPT; simultaneous wireless information and power transfer
