Wireless powering of biomedical device via magnetic resonance

Wireless power transfer efficiency of system based on the Strongly Coupled Magnetic Resonance (SCMR) is studied here for non-homogenous interfaces. Specifically, the SCMR wireless power transfer from a source in air to a sensor embedded in tissue is analyzed. A comparison of wireless power transfer efficiency between resonant loop and SCMR structure is shown. The efficiencies achieved in different types of tissue are also reported.
