Vibrotactile Haptics
This application uses heterogeneous frequencies to increase information transmission
New technological devices and paradigms have been developed to increase the effectiveness of rehabilitation by integrating multisensory information and augmented feedback promoting the involvement of the cognitive paradigm in neurorehabilitation.

Description
The majority of electronics offering haptic feedback use vibrations, and most use a type of eccentric rotating mass (ERM) actuator, consisting of an unbalanced weight attached to a motor shaft. As the shaft rotates, the spinning of this irregular mass causes the actuator and the attached device to shake. Piezoelectric actuators are also employed to produce vibrations, and offer even more precise motion than Linear Resonant Amplifiers(LRAs), with less noise and in a smaller platform, but require higher voltages than do ERMs and LRAs (Haptic technology, Wikipedia).
