Jan 1, 2025
This dosimetric study evaluated whether existing EM safety guidelines protect individuals with conductive implants by assessing implant-related local field enhancements. Across 10 kHz to 1 GHz, the authors report large increases in psSAR10mg and local electric fields near implants, particularly below 100 MHz. In…

This animal study examined whether EMF from a 90 kHz magnetic-coupling resonant wireless power transfer (WPT) system affects mouse cognition and hippocampal neuronal excitability. Mice were exposed for 2, 4, or 8 weeks and assessed with a Novel Object Recognition test and dentate gyrus patch-clamp recordings. The…

Jan 1, 2021
This engineering/methods study addresses computational artifacts that can affect coupling factor calculations for localized EMF exposure assessment in IEC 62311/62233, particularly below 10 MHz. The authors propose using the 99.99th percentile rather than the maximum internal quantity to mitigate abnormal peaks from…
