Tiivistelmä
Robustness evaluation is a critical part to verify the applicability of wireless implantable devices. In this work, we present a semi-anatomical ellipsoid head model to evaluate the robustness of a split ring resonator inspired antenna system toward variable implant location, tissue layer thicknesses, and antenna orientation with respect to the human head. The system consists of a passive wearable part placed on the scalp and a cortical implant that carries a passive UHF RFID microsystem. According to our results, the antenna system is robust toward variability: it enables the remote powering of a −18 dBm RFID microsystem at distance between 0.5 and 1.1 meter at various locations and orientations with respect to the head and for skull thickness up to 1 cm.
