PŚ scientists design neurological sensors
Novel neurological sensor, able to monitor intracranial pressure, was designed in cooperation with Centre of Research in Medical Devices (National University of Ireland, Galway), Imperial College London and University of Limerick.
Sensor was fabricated from a biodegradable and bioresorbable poly(glycerol sebacate urethane) (PGSU) composite, reinforced with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) functionalized carbon nanotubes (CNTs). Analysis of these PGSU-CNTs composites demonstrated that the incorporation of functionalized CNTs into a biodegradable elastomer resulted in enhanced mechanical strength, conductivity and tailored matrix biodegradation. PGSU-CNT composites were subsequently formulated into flexible and active pressure sensors, sensitive to small changes in pressure.
