Objectives: The aim of this study is to initiate research in the field of biomedical engineering geared towards a reduction of non-thermal effects on the brain due to the use of mobile telephones. This line of research employs devices attached to the back of cellular-telephone cases.

Methods: Under electromagnetic-environment controlled conditions EEG records have been obtained in 16 healthy subjects, with their eyes open at the base-line. These records were compared with the use of the mobile telephone with and without one of these devices for five minutes each, and having them statistically tested with Wilcoxon matched-pairs.

Results: Differences between experimental EEG, with and without the use of the device, have been observed. These subtle changes basically affect Delta and Theta wave bands. Their distribution, (changes in the affected areas of the brain), also varies, above all in the frontal areas.

Conclusions: The use of this device could reduce non-thermal effects of mobile telephones on the human EEG.
