Active implantable medical devices restore body function in patients with neurological or other disorders, increasing their quality of life. The RF-safety assessment of neural implants is complex due to the increasing use of multi-channel systems. In this study, the heating characteristics of intracranial EEG electrodes with increasing number of channels is investigated. this study shows that, for the given configurations, the RF-induced heating decreases, when the number of channels of the device is increased. Hence, increasing the grids of planar electrodes might be used to decrease the RF induced heating.
