Simulated midfield wireless power transfer (WPT) device assessed for optimal frequency for human tissue applications with complex tissue models.

1–2.5 GHz

More than 30 multilayer tissue models based on real CT images of humans were utilized in the simulations to determine the optimal frequency and calculate the coupling parameter and the SAR efficiency.

Cardiac pacemakers and other active implantable medical devices (AIMDs).

The simulations were validated with measurements with good agreement using a variety of non-human phantoms to demonstrate that the optimal frequency varied significantly with tissue composition and thickness.
