Optimizing Inductive Coupling and SAR Limits Across Cranial Tissue

Delivering electrical power wirelessly without exceeding Specific Absorption Rate (SAR) limits.

Specific Absorption Rate (SAR) Compliance

Inductive coils operating at 13.56 MHz induce eddy currents in vascularized scalp tissue. Coil geometry is optimized with ferrite shielding to keep localized SAR strictly below 2.0 W/kg.

High-Efficiency Resonant Coupling

Coupled resonant coils maintain over 72% electrical transfer efficiency despite angular misalignment and varying scalp thickness between patients.

Thermal telemetry shut-off if package surface temperature exceeds 38.5°C
Zero interference with external cardiac pacemakers or consumer NFC devices
Continuous real-time alignment feedback assisting patient coil placement
