We would like to point out that these are individual proofs. Everyone is different and the respective effects are therefore individual. The experiments presented here serve the possibility of being able to qualitatively classify the effectiveness of the Qi technology. Results of the studies do not reflect individual experiences, and individual results may vary.

Effects of the device Qi-Shield

Fraunhofer Institute for Industrial Engineering IAO

July 2021

A neurophysiological and psychological study to evaluate the effects of a lifestyle product

The Fraunhofer Institute for Industrial Engineering IAO works together with companies and public-sector bodies and institutions to develop strategies, business models and solutions for digital transformation.

From September 2020 to April 2021, the Fraunhofer Institute IAO scientifically examined the effects of the product Qi-Shield produced by the Waveguard GmbH on a psychological, psychophysiological and neurophysiological level in a study commissioned by Waveguard GmbH.

Waveguard is presently organising a follow on study to examine the results more deeply.

Qi-Shield & cultured connective tissue fibroblasts

Dartsch Scientific, Institute for Cell Biological Test Systems

Neutralisation of mobile phone radiation by Qi-Shield: Examinations with cultured connective tissue fibroblasts


31 December 2019

The study performed on cell (connective tissue fibroblasts) examined the effect of non-thermal radiation emitted by an active mobile phone on cell regeneration/wound healing in cultured cells. In addition, it also investigated if there is a protective effect of a Qi- Shield on cells exposed to mobile phone radiation.

The study results showed that cell regeneration and wound healing of connective tissue fibroblasts was strongly reduced by the non-thermal radiation of an active mobile phone, and that the use of the Qi-Shield neutralised this effect by approximately 90%.

Qi-Shield & protective influence for humans

Bion, Institute for Bioelectromagnetics and New Biology

Protective influence on human organism against wireless router radiation


9 August 2019

This study examined what happens to humans when exposed to a wifi router in vicinity, and in the presence of a Qi-Shield device. Electrophysiological parameters of 45 subjects were tested in total, divided into three groups (real Qi-Shield + wifi on, sham Qi-Shield + wifi on, and a control group).

The results of the study suggested that the Qi-Shield promoted relaxation in the study participants and had a protective influence on the study participants against wireless router radiation.

Effect of the Qi-Home Cell in a magnetic field with geopathic distortion and its effect on water


22 June 2017

In this study researchers examined whether the Qi-Home Cell has an effect on geopathic zones and water quality.

Authors reviewed the literature on different aspects of EHS and potential adverse health effects of RF-EMF, as well as case reports. Most people are unaware of this type of exposure, which has no smell, color, or visibility. There is an increasing concern that wireless use of laptops and iPads in Swedish schools, where some have even abandoned textbooks, will exacerbate the exposure to EMF.

In this article, the warnings on the health risks associated with RF presented in the 5G appeal and the letters to the EU Health Commissioner since September, 2017 and the authors’ rebuttals are summarized. The responses from the EU seem to have thus far prioritized industry profits to the detriment of human health and the environment.

The authors measured the radiofrequency (RF) radiation at central parts in Stockholm, Sweden in March and April 2017.

The main aim of this study was to compare earlier human epidemiological studies with US National Toxicology Program (NTP) findings, including a short review of animal studies. The authors conclude that there is clear evidence that RF radiation is a human carcinogen, causing glioma and vestibular schwannoma (acoustic neuroma). There is some evidence of an increased risk of developing thyroid cancer, and clear evidence that RF radiation is a multi‑site carcinogen. Based on the Preamble to the IARC Monographs, RF radiation should be classified as carcinogenic to humans, Group 1.

In the present study, the levels of RF radiation were measured in an apartment close to two groups of mobile phone base stations on the roof. Due to the current high RF radiation, the apartment is not suitable for long-term living, particularly for children who may be more sensitive than adults.

In the article the authors discuss the following: In 2014 the WHO launched a draft of a Monograph on RF fields and health for public comments. It turned out that five of the six members of the Core Group in charge of the draft are affiliated with International Commission on Non-Ionizing Radiation Protection (ICNIRP), an industry loyal NGO, and thus have a serious conflict of interest. Just as by ICNIRP, evaluation of non-thermal biological effects from RF radiation are dismissed as scientific evidence of adverse health effects in the Monograph. This has provoked many comments sent to the WHO. However, at a meeting on March 3, 2017 at the WHO Geneva office it was stated that the WHO has no intention to change the Core Group.
