Development of Piezoelectric Micropyramid Balloon Catheter Sensor for Measuring Vascular Stiffness

The research team, led by Professor WonHyoung Ryu from the Department of Mechanical Engineering (co-first authors of this study are Yosup Kang and JiYong Lee), has developed a piezoelectric balloon catheter sensor using a micro-pyramid structure composed of flexible piezoelectric nanocomposite materials.
It has been demonstrated that this piezoelectric balloon catheter sensor can be utilized for the diagnosis of cardiovascular diseases by directly measuring the mechanical strength of lesion areas within blood vessels. This research has been published in the renowned international academic journal 'ACS Applied Materials & Interfaces' (Impact Factor: 10.383) in April 2023.
