Orthogonally oriented coils for minimization of cross-coupling in cortical implants
This article presents the design of the inductive links of remotely powered wireless cortical implants for minimum interference from the power link to the data link. This interference is minimized by changing the orientation of the inductors. Different orientation types are investigated and compared. Orthogonally oriented coils with high interference suppression and better reproducibility has been proposed. From the simulations, 29% power efficiency and 46 dB interference suppression is achieved for these coils. The spiral inductors are fabricated on PCBs and results of preliminary measurements are presented. Moreover, a conceptual cortical implant prototype is proposed.
