APPLICATION OF FIBER-OPTIC SENSORS AND SENSING SYSTEMS FOR DYNAMIC MONITORING OF BRAIN BIOMARKERS IN TRAUMATIC BRAIN INJURIES

Abstract

The study examines the specific features of using fiber-optic sensors for monitoring key brain biomarkers employed in the detection and prevention of complications in traumatic brain injuries. Proposals for the development of multiplexed sensors capable of simultaneously measuring up to four parameters are discussed. Promising designs of a biologically dissolvable sensor based on a Fabry–Perot interferometer and photonic crystal structures are presented. It is concluded that fiber-optic sensors make it possible not only to perform high-precision measurements of physiological parameters but also to enable the early detection of brain tissue damage and the assessment of the effectiveness of therapeutic interventions.
