<div><p>A magnetorheological elastomer peristaltic fluid conveying system consisting of a magnetorheological elastomer tube and two electromagnets implements controlled movements via an external magnetic field with varying periods of driving voltages to convey non-Newtonian fluids over a certain time period. The effects of backpressure at the outlet of the magnetorheological elastomer peristaltic fluid conveying system, the viscosity of fluids at zero shear rate, and moisture loss along the longitudinal direction on net pumped volume are investigated systematically. The results demonstrate that the net pumped volume declines linearly with backpressure under all driving voltage periods. An improvement of the viscosity of fluids at zero shear rate allows at first the decrease, then the increase, and finally the decrease of the net pumped volume. Moisture loss plays a second role in the net pumped volume and the change of the fluid viscosity profile. The compression of the magnetorheological elastomer tube, the maximum shear stress, and the maximum von Mises stress in the magnetorheological elastomer peristaltic fluid conveying system are investigated to evaluate the magneto-fluid-structure interaction. This research offers a new approach to biological fluid conveying with an analogic moisture loss process.</p></div>
