There are a number of esoteric companies offering stickers that they claim can reduce the effect of unwanted electromagnetic fields (so-called electrosmog) on biological organisms in the near proximity of the electronic device (e.g. mobile phone). Backed up with scanty, if any, scientific evidence. And by scientific evidence, I mean a clear hypothesis, tests designed to isolate a single variable, and statistical results as opposed to pretty pictures. Well… here’s one company which has published some scientific findings regarding the effectivity of their products – and I commend them for doing so! Ignoring the fact that the leading scientist seems to have no credible research papers published to his name, let’s take a look at the results.
Test in 2011: this actually looks like they might be onto something. Not only a clear description of the test methodology, but also astounding results in section 4.3. To quote the conclusion: “The compensation potential is up to 100% for disruptions of up to 0,4 Microtesla, and beyond that 50%.” So there you have it: measured effectiveness of 50% for the claimed capabilities of electromagnetic field restoration. http://waveex.at/uploads/page_Gutachten_Medinger.pdf
Repeated test in 2014 (no idea if there were any ‘research developments’ on how to make that sticker ‘better’ between 2011 and 2014): forget that previous result. This repeated test shows that can nice results can only be achieved by selectively choosing measurement points to create a ‘positive’ conclusion. (More concretely: the sticker does have a minimal effect, which starts to be effective at a distance of 20 cm from your mobile phone, and not at the typical 1cm distance you’d hold a phone at when you talk on it.)
Surprise, surprise, it looks like the sticker makes very little difference after all!
