Conductive textiles as an electromagnetic shield

The paper deals with possible short and long term effect of electromagnetic radiation on both human organisms as well as on operation of electronic devices due to electromagnetic interference. Some sort of shielding is required in order to protect humans and electronic equipment from electromagnetic radiation. Conductive textiles can be used as a protection of people and electronic equipment from electromagnetic fields due to their characteristics: light weight, metal threads acting as an electromagnetic shields and easy maintenance. Usually conductive fibers are made of copper, nickel, silver or inox (steel) threads. The attenuation of electromagnetic wave on microwave frequencies (900MHz–2400MHz) is between 20dB and 60dB. Conductive textiles are subject to changes in the environment, namely to the ultraviolet light, dirt, thermal radiation and moisture. The maintenance of conductive textiles has been considered (washing and chemical cleaning) as well as influence of cleaning on the characteristics of electromagnetic shield properties. The advantage of conductive textiles is in its lightweight and lower expenses compared to some other methods of shielding as well as the possibility of easy replacement after wearing out. Conductive textiles can be used as barriers from electromagnetic radiation coming from GSM base station antennas as well as possible protection from 5G technology in kindergartens, schools, farms, in agriculture, etc…
