Reconfigurable interfaces offer new prospects for intuitive human-machine-interfaces. In this paper, we investigate the design and application of magneto-rheological elastomer (MRE) based actuators for the use in a reconfigurable joystick. MREs consist of magnetisable particles, embedded in an elastomer matrix. Thus they provide a base elasticity. By using external magnetic fields, the storage and loss modulus can be manipulated. We developed two actuators, one with prominent elastic and one with damping characteristics. The development is based on a simplified material model, measurements and simulation. The actuators achieve forces up to 60 N, resulting in a reaction torque of up to 0.4 Nm. The damping actuator achieves a loss modulus increase of 82 kPa.
