Tunable Properties of Magnetoactive Elastomers for Biomedical Applications

The remote controllable magneto-mechanical devices based on MAEs (magnetoactive elastomers) can be obtained through variation of magnetic parameters of MAEs. Such devices can be used as the elements of peristaltic systems, artificial muscles, hyperthermia or drug delivery. MAEs with different matrix rigidity and filler particles type were investigated with VSM Lakeshore 7400 series and immittance meter Aktakom AM-3016 model. The dependencies of magnetostatic and magnetodynamic properties of MAEs with different types of magnetic particles on concentration of the magnetic filler and DC magnetic field strength were studied. There is a possibility to control the “magnetic hardness”, energy absorption and heating, relaxation properties of MAEs which allow to use MAEs as the main element of the tunable devices for biomedical applications.
