Highly Efficient Wireless Power Transfer Systems for Wearable and Implantable Devices

The effects of the human body on wearable and implantable Wireless Power Transfer (WPT) systems, which are based on the Conformal Strongly Coupled Magnetic Resonance (CSCMR) method, are studied. Specifically, a CSCMR system's efficiency in free space is compared to its efficiency at several locations on and inside the human body. Simulations were performed using the EM SIM4LIFE software and a detailed human body model (i.e., Duke). The effects of the head, chest, and lower back are examined for wearable applications.
