Local temperature assessment produced by an implantable antenna for intracranial pressure monitoring

This study focuses on the local temperature elevation produced by a biocompatible dual-band implantable antenna which is designed for Intracranial Pressure Monitoring (ICP) application. A numerical analysis of the temperature elevation is being performed based on the Pennes Bioheat Equation (PBE) in both MedRadio and Industrial, Scientific and Medical Radio (ISM) band. The induced heat dissipation inside a human anatomical model is being examined. A maximum temperature elevation of 0.192°C is observed in the close proLüty of the implantable antenna under compliance with the IEEE basic exposure limitations.
