Abstract

Magnetoactive soft elastomeric membranes are versatile structures that find applications in various fields such as soft robotics, microfluidics and diaphragm pumps. For diaphragm pumps, magnetoactive soft elastomers with both soft and hard ferromagnetic particles have been investigated. However, the temperature rise effects in such magnetoactive soft elastomeric membranes for diaphragms have not yet been investigated. In this study, we have developed magnetoactive soft elastomeric membranes based on thermoplastic elastomer as the polymeric matrix and carbonyl iron or manganese ferrite as ferromagnetic and ferrimagnetic fillers, respectively. Using material extrusion-based additive manufacturing (MEX-AM), magnetoactive soft membrane structures have been fabricated to investigate the magneto-active deformation and temperature rise in such structures. With a custom-built setup a magnetic field in the form of a step-response was applied to the magnetic structure utilizing an electromagnet and the deformation was measured using a laser distance sensor. In this work, we exploited the heating of the electromagnet, due to high voltage and long run-time, to introduce a temperature rise in the magnetoactive membranes. A higher temperature rise due to the heat dissipated by the electromagnet is observed in the membrane with manganese ferrite particles. From the magnetoactive deformation results it was observed that at low magnetic fields both ferromagnetic and ferrimagnetic structures demonstrate similar magnetoactive performance, however, with an increase in magnetic field strength the ferromagnetic structure shows up to four times higher magnetoactive behavior. Such magnetoactive membranes with both magnetoactive deformation and temperature rise can find applications in diaphragm pumps for transferring fluids and additionally, heating the fluid in contact.
