Non-invasive biomedical patch sensor to measure intracranial pressure

Abstract

This study was focused on the development of a non-invasive mobile skin sensor for measuring intracranial pressure (ICP). Current techniques are limited to surgical implantations or methods that require highly specialized equipment and training. Additionally, surgical implantations carry risk of infection. To overcome these disadvantages we designed an electromagnetic resonance skin sensor patch to measure ICP. Fluctuations in the sensor's magnetic field were correlated with volumetric changes inside the cranial cavity of a human skull. These results provide evidence for an innovative method which avoids the disadvantages of current methods.
