Abstract (in Japanese) (See Japanese page) 
(in English) We have found human peripheral blood flow change associated with ELF (Extremely Low Frequency, 0-300 Hz) electric field exposure. When the ELF electric field is exposed to a human body with electrodes insulated from the body, low-frequency mechanical vibration occurs around the electrode at close contact to the body. An experimental study was conducted to find whether the blood flow change was caused by this vibration or electric field itself. First, the environmental effect of an experiment was investigated. It was confirmed that the effect of electric field exposure is larger in humid atmosphere than dry one. Then, the electric field and the mechanical vibration were applied to a human body, and the blood flow was measured. In the vibration exposure, blood flow increased locally near the applied area. In the field exposure, blood flow increased at all body surface of the subject. Finally, to differentiate the cause of the blood-flow increase, the effect of mechanical vibration was eliminated using a vibration absorbing material. It was found that blood flow still changed in the electric field exposure even without mechanical vibration.
