Method to Measure Intracranial Pressure Wirelessly Using Remote Powering by Ultrasound

Abstract

Over 14 million people are affected by increased intracranial pressure (ICP) due to traumatic brain injury or conditions like hydrocephalus, which causes excess cerebrospinal fluid in the brain. This research aims to develop and test a novel remote impedance measurement system (RIMS) that uses wireless power transfer between an external ultrasound emitter and an implanted piezoelectric receiver to monitor cerebral bioimpedance. The system will be validated with bioimpedance data from a controlled conductivity solution and will be used to correlate ICP with cerebral bioimpedance, providing a real-time, innovative solution for ICP monitoring.
