Sensorless Viscosity Measurement in a Magnetically-Levitated Rotary Blood Pump

Controlling the flow rate in an implantable rotary blood pump based on the physiological demand made by the body is important. Even though various methods to estimate the flow rate without using a flow meter have been proposed, no adequate method for measuring the blood viscosity, which is necessary...
