Abstract
Typically, the displacement of piezo-electric actuators is quite small. Accordingly, some sort of amplification may be needed for specific applications to amplify the displacement of the piezo-electric actuator, and thereby amplify the haptic feedback. For all solutions, the goal is to amplify the displacement of a moveable mass in order to increase vibration to improve the haptic feedback. If the host device is a wearable or portable device, e.g. a smart watch, it would be preferable to excite a heavy moveable mass that is already part of the assembly to harvest enough energy to transmit to the interface with the user. If the device is a large display, e.g. a display in a vehicle info system, the display itself could be the moveable mass.
