The PiezoTac Tactor designs are based on piezoelectric actuators that have been optimized for use against the skin. It uses the lowest operating voltage of any piezo actuator in its class and provides a strong point-like sensation that is easily felt and localized. Operating below its mechanical resonance (300-350 Hz) the device has a very wide operational bandwidth (100-290 Hz). The PiezoTac’s high force and displacement level allow the vibration to be easily felt at all locations on the body, even through layers of clothing. The PiezoTac tactor contains no significant magnetic materials, and can be configured for high magnetic field environments (MRI). The PiezoTac and Mini PiezoTac designs require an EAI proprietary controller.
