Abstract

The development of biocompatible, energy-efficient pumping mechanisms is pivotal for advancing artificial heart (AH) technology. This study explores a motor-driven centrifugal pump designed to replicate the physiological dynamics of natural ventricles while mitigating complications associated with conventional axial and pulsatile systems. The proposed system employs a brushless DC motor with closed-loop control, integrated with pressure and flow sensors to modulate rotational speed (RPM) and generate biomimetic cardiac output. The suggested system combines a closed-loop control approach, a centrifugal impeller, and a brushless DC motor. Continuous hemodynamic data from real-time pressure and flow sensors allows for adaptive motor rotational speed regulation to produce biomimetic cardiac output. After evaluating flow behavior, shear stress distribution, and thrombogenic potential through computational fluid dynamics (CFD) simulations, hydraulic performance was verified in vitro using a blood-analog fluid. Computational fluid dynamics (CFD) simulations and in-vitro trials using a blood analog fluid demonstrated that the motor-driven pump achieves a mean flow rate of 5.2 L/min at 3000 RPM, with a hemolysis index of 0.05 g/dL and thrombogenic potential reduced by 40% compared to existing AH models. Energy consumption metrics revealed a consumption rate of 8.3 W, enabling 12-hour operation from a lithium-polymer battery. The system’s adaptive feedback mechanism, which adjusts motor load in response to real-time hemodynamic demands, was validated under simulated rest and exercise conditions, ensuring stroke volumes within physiological ranges (50–80 mL). These findings underscore the motor-integrated pump’s potential to enhance cardiac output while preserving erythrocyte integrity and minimizing energy overdraw, addressing critical limitations in current AH platforms.
