Extremely Low Frequency (ELF) electromagnetic signals are of great interest in a variety of applications, including the transmission of communication signals over long distances in seawater and below the Earth’s surface, deep geophysical sounding, and the study of electrical atmospheric phenomena known as sferics. In subsurface signaling applications, wireless electromagnetic methods generally ...

During recent years there has been increasing public concern on potential health risks from power-frequency fields (extremely low frequency electromagnetic fields; ELF) and from radiofrequency/microwave radiation emissions (RF) from wireless communications. Non-thermal (low-intensity) biological effects have not been considered for regulation of microwave exposure, although numerous scientific ...

The extremely low frequency (ELF) radiation from various laptops and monitors model was investigated using a cell sensor manufactured by Action Electronic, USA that is optimized to measure radiofrequency and extremely low frequency radiation. The ELF measured vary between 0.05 and 2.5 mG for all the laptops/monitors studied however, Hp Pavilion dv6000 laptop was considered to emit highest ELF i...

Touch sensing is a fundamental approach in human-to-machine interfaces, and is currently under widespread use. Many current applications use active touch sensing technologies. Passive touch sensing technologies are, however, more adequate to implement low power or energy harvesting touch sensing interfaces. This paper presents a passive touch sensing technique based on the fact that the human b...

Extremely low-frequency electromagnetic fields (ELF-EMFs) can affect male reproductive function, but the underlying mechanism of this effect remains unknown. miRNA-mediated regulation has been implicated as an important epigenetic mechanism for regulatory pathways. Herein, we profiled miRNA expression in response to ELF-EMFs in vitro. Mouse spermatocyte-derived GC-2 cells were intermittently ex...

Penelitian ini bertujuan untuk menganalisis potensi peningkatan kualitas apabila menggunakan medan (ELF). Metode penelitian yaitu Article Review Pengumpulan data dilak...

INTRODUCTION The present study investigated the interactive effect of GABAB receptors and extremely low frequency electromagnetic field (ELF-EMF) on foot shock-induced aggression in rats. METHODS Fifty adult male rats were randomly assigned into 10 groups. Groups 2, 4, 6, 8 and 10 were exposed to 50 Hz, 500 µT ELF-EMF for 30 days 8h per day while the remaining groups (1, 3, 5, 7 and 9) were s...

This paper surveys the instrumentation, calibration procedures, measurement techniques, and standards which can be used to characterize extremely low frequency (ELF) electric and magnetic fields. While the focus of the paper is on power frequency and power frequency harmonic fields, the measurement methods discussed are appropriate in principle for other ELF frequencies.
