Arterial plaque, or atherosclerotic plaque, forms when fatty deposits, cholesterol, inflammatory cells and other materials accumulate within the arterial wall. The approach is based on electrical impedance, a property describing how strongly tissue resists or conducts an applied electrical signal. That contact is critical because electrical impedance measurements are sensitive to the distance and interface between the sensor and tissue. Subject of Research: A stretchable liquid-metal balloon catheter for high-resolution three-dimensional electrical impedance mapping of metabolically active arterial plaque.
