Wireless energy transmission technology and its application in a torque monitoring system

To transmit energy continuously to the monitoring system on a rotate part and to make the system stable, an energy transmission technology based on microstrip antennas was put forward. An overall project of the energy transmission system for microstrip antennas was provided for the energy input of transmission antennas, and a separate scheme of power supply was proposed. The energy transmission conditions of a pair of antennas and multi-pairs of antennas were investigated. The crisscross motion conditions ofmicrostrip antennas were analyzed. The results indicated that the energy transmission scheme could meet the demands of practice.
