New standard for wireless power transfer exposure assessment

Wireless power transfer (WPT) systems are revolutionizing how we power our devices, from electric vehicles to smartphones. As these systems become more widespread, though, how do we ensure that prolonged exposure to them is safe

IEC/IEEE 63184:2025 addresses this critical need by providing the world’s first comprehensive methods to assess human exposure to electromagnetic fields (EMF) generated by WPT systems. This dual-logo standard, developed jointly by the IEC and the Institute of Electrical and Electronics Engineers (IEEE), marks a significant milestone in the field of electromagnetic safety

?Why is this standard important

WPT systems operate by transferring energy through electromagnetic fields, typically in the frequency range of 3 kHz to 30 MHz. While these systems are designed to be safe, it is essential to evaluate their impact on human health

Human exposure to EMF is limited to avoid established adverse health effects, including electrostimulation of nervous tissues (3 kHz < 10 MHz) and thermal effects (> 100 kHz)

“IEC/IEEE 63184 provides guidance on best practice methods to assess exposure. This helps to ensure that WPT systems comply with international safety guidelines, such as those set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP)

:The new international standard focuses on three key areas

Specific Absorption Rate (SAR) to measure how much energy is absorbed by the body

Internal Electric Fields and Current Density to assess the electric fields and currents induced within the body

Contact Currents to evaluate currents that flow when a person touches a conductive object in the presence of an electromagnetic field

IEC/IEEE 63184 provides clear procedures for measurement, computational modelling and combined assessment methods to ensure that WPT systems are safe for public use

Promoting sustainability and well-being

IEC/IEEE 63184 also supports sustainable development. It encourages the adoption of energy-efficient technologies that reduce environmental impact by standardizing the evaluation of WPT systems

Wireless power transfer eliminates the need for disposable batteries and reduces electronic waste, contributing to a cleaner, greener future. Safe and reliable WPT systems enhance well-being by enabling innovative applications in healthcare, transportation, and consumer electronics

Looking ahead

While IEC/IEEE 63184 addresses WPT systems operating at frequencies up to 30 MHz, the work continues. The IEC and IEEE experts are now developing evaluation methods for radiative WPT systems operating at higher frequencies (30 MHz to 300 GHz)
