With the development of ultra-low power consumption integrated circuit technology,the power consumption of electronic micro-system is reduced to a micro-watt(μW) magnitude,so it is possible for the electronic micro-system to power itself by harvesting ambient radio frequency( RF) energy. Based on the introduction about the wireless power transmission and the feasibility, development and applications of ambient RF energy harvesting technique, the key techniques, challenges and possible solutions of the im-plementation and wide applications are discussed. Finally, the developing trend of the ambient RF energy harvesting technique is presented, making the research issue and its direction more idiographic and specific.
