Minimizing electromagnetic exposure for wireless mm-size neural implants

Résumé

Wireless neural interfaces provide major leap capabilities for neurotechnology by removing hazardous and bulky percutaneous links. This study addresses for the first time the radio frequency (RF) electromagnetic (EM) exposure of mm-sized neural implant antennas in the frequency range from 100 MHz to 4 GHz. The results demonstrate the existence of mode-dependent optimal radiating conditions that minimize the total dissipated power and Specific Absorption Rate (SAR) for a given input power. Peak SAR is in average 3.7 times lower for the magnetic source than for the electric one. This study provides decision-making insights into how to design EM-safe and efficient antennas for mm-sized wireless implants.
