Abstract EN
This paper examines system optimization for wirelessly powering a small implant embedded in tissue.
For a given small receiver in a multilayer tissue model, the transmitter is abstracted as a sheet of tangential current density for which the optimal distribution is analytically found.
This proposes a new design methodology for wireless power transfer systems.
That is, from the optimal current distribution, the maximum achievable efficiency is derived first.
Next, various design parameters are determined to achieve the target efficiency.
Based on this design methodology, a centimeter-sized neurostimulator inside the nasal cavity is demonstrated.
For this centimeter-sized implant, the optimal distribution resembles that of a coil source and the optimal frequency is around 15 MHz.
While the existing solution showed an efficiency of about 0.3 percent, the proposed system could enhance the efficiency fivefold.
