Effect Of Low-power Wireless Power Transfer System On Menory Behavior And Partial Physiological Properties Of Mice

Wireless Power Transfer(WPT)is a new type of charging technology,which can not only effectively overcome inflexibility of traditional wired charging,but also has more characteristic include higher utilization and more convenience.It is playing an increasingly stronger role in many fields,such as electric vehicles,underwater facilities,home electronics,implanted medical equipment,industrial equipment and aerospace.With research and development of WPT,the efficiency and stability of the system have gradually reached requirements.Electromagnetic safety of WPT will be received more attention if this system is widely used in electronic and electrical equipment.According to the current research status of WPT,research the electromagnetic safety of WPT in this paper as follows:(1)Several main advantages are analyzed among different classification of WPT,and research status of WPT system and electromagnetic safety are introduced in detail.(2)From the perspective of electromagnetic biological safety,classification of biological effect is summarized,and authoritative electromagnetic protection standards at home and abroad are compared.(3)The principle and transmission efficiency of WPT via magnetic coupled resonances are analyzed.And a low-power WPT system is built,electromagnetic environment of exposed area is measured by three-dimensional electromagnetic radiation analyzer.(4)A long-term exposure experiment of mice are carried in the established WPT system lasting for 12 weeks,and behavioral experiment of mice are performed to test whether the memory behavior of mice has been affected in the WPT system.(5)The mice are dissected after the expose experiment,the immune parameters,sex hormone,and physiological structure of partial organs of mice are detected whether the physiological properties have been affected under long-term exposure in low-power WPT system.
