The Science of Wireless Charging
Wireless charging, also known as inductive charging, works by transferring energy between two coils: a transmitter coil in the charging base and a receiver coil in the device to be charged. When an alternating current (AC) flows through the transmitter coil, it generates a magnetic field, which induces an electromotive force (EMF) in the receiver coil. This EMF is then converted back into an electrical current, powering the device.
The key to understanding the potential health risks of wireless charging lies in the EMF generated during the process. EMFs are a form of non-ionizing radiation, which is different from ionizing radiation found in X-rays and gamma rays. While ionizing radiation has been proven to cause cancer, the scientific consensus is less clear when it comes to non-ionizing radiation.
Existing Research on Wireless Charging and Cancer
Several studies have investigated the potential link between wireless charging and cancer. Here are some key findings:
-
A 2019 study published in the Journal of Exposure Science and Environmental Epidemiology found no evidence of a link between wireless charging and cancer. The researchers analyzed data from over 1,000 participants and concluded that exposure to wireless charging EMFs did not increase the risk of cancer.
-
A 2017 review of 23 studies on radiofrequency electromagnetic fields (RF-EMFs), which include wireless charging EMFs, found that the evidence for a link to cancer was “inadequate” and “limited.” The review, published in the International Journal of Environmental Research and Public Health, emphasized the need for further research.
-
The World Health Organization (WHO) has classified RF-EMFs as “possibly carcinogenic to humans,” but notes that the evidence is limited and that more research is needed to fully understand the potential risks.
