Loop Antenna for Deep Implant Powering in an Intracranial Pressure Monitoring System

This paper presents a loop antenna for deep implant powering in an intracranial pressure (ICP) monitoring application. This work is continuation of our on-going development of a wirelessly powered implantable system for ICP monitoring. Experimental results indicate that the implant can be activated until the depth of 19 mm from the skin. This is 8 mm more than our previous work where we were able to activate the implant until 11 mm depth from the skin. Moreover, we have also presented pressure readout experimental results with the proposed antenna.
