ABSTRACT
The application of the magnetostriction effect of MSE, i.e. the magnetically induced shape change, for sensor systems is very effective with relatively soft materials, because a decrease of the deformation ε is approximately proportional to the inverse square root of the elasticity modulus E (Foster at al. 2012). Classic elastomer composites are produced by cross-linking of long chains during the curing process and contain reinforcing fillers. Accordingly, the effect of magnetostriction of these relatively stiff elastomer composites is low. However, the elastic modulus of MSE composites can be increased spontaneously by about 30%, if an external static magnetic field is applied (Aloui & Klüppel 2015, McIntyre et al. 2012). This could significantly affect the resonance frequency and the damping behavior of the adaptive components (Deng et al. 2006).
