In the study of biological effects of extremely low frequency (ELF) electric fields, a few techniques were developed which enable us to measure the electric field at a biological body surface with practical accuracy and spatial resolution. They are: 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.
