MAGPy3 is a stand-alone system that is easy-to-use for in situ exposure assessment and compliance testing of WPT systems and any other strong magnetic near-field sources.
The probe is constructed of 24 small time-domain (TD) loop sensors arranged on the corners of a cube for determining the magnetic (H/B-) field amplitude and gradient, and of two dipole sensors and a monopole sensor to measure the electric (E-) field amplitude simultaneously.
The induced fields (internal E-fields, current density, and specific absorption rate (SAR)) in the human body at any position are instantly determined using the novel GMMS (Generalized Multipole Amplitude and Gradient Method) defined in IEC/IEEE 63184:2025 and compared to basic restrictions and reference levels.
The system is highly accurate and minimizes overestimation (up to 40 dB) compared to conventional devices. MAGPy V3 is fully compatible with the latest IEC/IEEE 63184:2025 standard.
DASY8 Module WPT is the most accurate method to assess WPT exposure. It integrates MAGPy technology into our DASY8 product line for high-precision, 3D robot-based scanning. It is the leading automated solution for demonstrating compliance of WPT devices according to the latest requirements of IEC/IEEE 63184:2025 (succeeding Chapter 8 of the original PAS version) and enables fully automated compliance testing.DASY8 Module WPT is composed of one isotropic magnetic sensor and a reference sensor connected to the MAGPy data acquisition system (MAGPy-DAS) and mounted to the DASY8 robot. The induced E-fields and SAR are assessed with Sim4Life’s Quasi-Static Electromagnetic Solver (P-EM-QS) using only the measured data. The dedicated graphical user interface fully automates the testing workflow.The module determines the compliance of WPT systems and magnetic field sources without overestimation. It is also more accurate than simulation-based evaluations as it is grounded on actual field measurements and does not require geometric modeling of the device.
- Applications
The two systems accurately measure the electromagnetic (EM) field in the time-domain at any high-field configuration and are especially suited to evaluate human exposure. Applications include:
- Automotive/vehicular/train WPT
- Industrial and utility (e.g., industrial welding, induction cooking, electronic article surveillance, and WPT)
- Energy supply (e.g., installation and operators of WPT networks)
- Ubiquitous devices equipped with WPT technologies (e.g., mobile phones, implantable medical devices, wearable devices, and Internet of Things (IoT))
- High power electromagnetic (EM) sources
- EM Safety Guideline Compatibility
Both systems permit compliance testing of devices with current guidelines for both the general public and occupational exposures, including: FCC, ICNIRP 1998, ICNIRP 2010, IEEE C95.1 2005, EU Directive 2013, HC Code 6, BGV B11, 26.BlmSchV.
