Intersubject assessment of implantable antenna performance for intracranial pressure monitoring

This work focuses on the assessment of an implantable antenna performance designed for Intracranial Pressure (ICP) monitoring applications. A simplified three-layer canonical model, exclusively designed for antenna tuning inside anatomical human head, is evaluated. Inter-subject variability is studied using four different human head anatomical models which are part of the Virtual Family by Foundation for Research on Information Technologies in Society (IT´IS) and have been extensively used in the literature. Simulations are performed within MedRadio band, which is worldwide available, and has been allocated exclusively for medical applications. The results highlight the suitability of the proposed simplified model for antenna fine-tuning. Moreover, no significant detuning effects are observed among the anatomical models, as the antenna maintain sits resonance, radiation and safety performance.
