The world of haptic is an emerging field of research with rapidly evolving technologies. Researchers are still looking for the optimal solution to create a haptic device that can provide a realistic touch sensation. Vibrations, forces, and temperatures are the stimuli involved in the majority of the touch experience. For what concerns the rendering of texture, i.e., generating vibratory cues, the most widespread technology is high-performance piezo actuators, but even if this technology has multiple limitations. The most critical ones are their limited capability of generating low-frequency responses and their lack of flexible models. These characteristics are crucial for the creation of a realistic haptic interface that could also be easily integrated into wearable devices.
