EMX biochips are a technology based on genuine scientific research. These are not the same as “protection devices” that are widely marketed yet have no real effect (other than placebo). The EMX devices work on the basis of superimposing random, low frequency magnetic fields over other electromagnetic fields (EMFs) being emitted by other devices. The theory behind this is that the extra fields hide the unwanted EMFs, in a similar way to music being played in a restaurant hides conversations between other people on nearby tables. A number of peer-reviewed scientific studies have been carried out and replicated, showing that this has genuine scientific basis. While this appears to be effective, we do not think that increasing EMFs is an ideal solution, and we believe that other options should be explored first.
