The actuator is based on a unimorph design that consists of a multilayer piezo element bonded to one side of a vibration plate.
This unimorph structure enables the device to adapt to temperature and shape challenges, and allows it to obtain a clear response while still driving with low voltage.
The actuator can be driven with voltages as low as 24V and can produce a variety of vibration patterns depending on the amplitude and frequency of the voltage applied.
At a frequency of 200Hz and a voltage of 24V peak, the actuator offers a typical displacement of 65 µm (without load).
The PiezoHapt ultra-thin actuator is now in stock at Mouser Electronics in an 80 × 60mm vibration plate footprint and represents an ideal power-saving haptic solution.
Providing a wide range of vibration patterns, it is ideal for haptic feedbackapplications in devices such as smartphones, wearables, tablets, displays, touchpads, and industrial controls.
