Abstract :
In a study of biological effects of extremely-low-frequency (ELF) electric fields, a few techniques were developed which make it possible to measure the electric field at a biological body surface with practical accuracy and spatial resolution. The following techniques were developed: pressing down a field sensor against the body surface using a thin flexible sensor: and covering the body surface with a conductive layer while leaving the point of measurement uncovered. The characteristics of these techniques were also examined with a view toward practical applications, such as the measurement of the electric field at a human surface located under high-voltage transmission lines
