Our latest journal article‚ “Design and Characterization of a Magnetic Silicone Peristaltic Pump With Multiphysics Modeling” is now available via IEEE Xplore in IEEE/ASME Transactions on Mechatronics.

In this article, we report on the development of a magnetic peristaltic pump for microfluidics, bioengineering or medicine that does not require rollers and thus reduces abrasion and mechanical stress. This pump is maintenance-free and operates silently due to the magnetic actuation. To evaluate the performance of the pump, we carried out both simulations and experimental measurements and achieved good agreement. A multiphysics model was developed and validated to simulate the dynamic behavior of the system, including transient flow rate, pressure, wall shear stress and Reynolds number. The simulation results show evenly distributed shear stress with peak values below 25 Pa during blood transport, which corresponds to a reduction in peak and time-integrated shear stress of about 50 % compared to roller pumps. In the pumping tests, a maximum flow rate of 130 ml/min, a peak back pressure of 4 kPa and a maximum suction height of 35 cm were achieved. Get it here: https://ieeexplore.ieee.org/document/10872894
