A protective enclosure designed to mitigate the user’s exposure to electromagnetic field (EMF) radiation emitted by mobile telephones. These products typically incorporate materials intended to absorb or deflect a portion of the energy transmitted by the device during operation. An example would be a wallet-style cover with a lining of specialized metallic fabric.
The potential benefits of using such a product center on reducing direct contact with radiofrequency energy. Historically, concerns about the long-term effects of cellphone radiation exposure have fueled consumer interest in protective measures. Consequently, manufacturers have developed a variety of shielding technologies integrated into these accessories.
