Temperature elevation produced by miniature implantable antennas for Intracranial Pressure Monitoring

摘要

This study focuses on the assessment of the temperature distribution produced by a dual-band implantable antenna used for Intracranial Pressure Monitoring (ICP). A numerical analysis of the Specific Absorption Rate (SAR) distribution and the induced heat dissipation is presented in a spherical human head model. A temperature elevation of 0.5–2.7°C is produced in the close proximity of the implantable antenna under compliance with the latest IEEE basic exposure limitations.
