Issues in Wireless Intracranial Pressure Monitoring at Microwave Frequencies
Intracranial pressure (ICP) monitoring has a significant role in the diagnosis and prognosis of various brain diseases. The most prevalent technique of monitoring ICP is using catheter based systems, which involve risks including infection, brain damage and patient discomfort. A novel wireless epidural pressure sensor unit which can be implanted in a burr hole drilled in the skull is proposed. The unit operates at an ISM band of 2.4 GHz and radiates a microwave signal as a function of pressure. In-vitro and in-vivo tests were performed to study the e±ciency of this measurement technique. This paper presents the design issues and experimental results of the prototype devices developed so far.
