Development of a Magnetorheological Elastomer Actuator for a Mixed Reality Haptic Glove
IEEE/ASME International Conference on Advanced Intelligent Mechatronics, AIM
The implementation of wearable haptic devices has enabled fully immersive environments to be implemented in virtual and augmented reality applications. Advances in these technologies utilize various methods and stimuli to develop realistic sensations of touch, with a key focus area on the hands and fingertips. In haptic devices, magnetorheological elastomers (MREs) are yet to be fully explored, providing an opportunity for an application of an MRE haptic actuator to a wearable haptic glove. Through application of established MRE modelling techniques such as magnetic field simulations, a novel design of an MRE haptic actuator is developed. The device is then experimentally characterized, showing a maximum output force of 161 mN, increasing linearly with current supplied to the included electromagnet. Some paths towards optimization are then explored for improving output force and miniaturization before investigation of an experimental approach to integrate with mixed reality technologies.
