Research of Electromagnetic Wave Energy-Harvesting Technology on Free Space
In order to provide long-term power supply for low-power consumption and many wireless sensor nodes, it is proposed to replace the battery and the power supply line by harvesting space radio wave energy to make up for the trouble of replacing the battery and reduce environmental pollution. Dickson rectifier voltage multiplier circuit is constructed by using schottky diode with low conduction voltage when a radio frequency of 400 MHz and a voltage amplitude of 5 mV is input, the rectified output DC voltage reaches 20 uV. This scheme provides a reference for wireless power supply of low power class circuits.
