The TDK PiezoHapt actuator, available from Mouser Electronics, is based on a unimorph design consisting of a multi-layer piezoelectric element bonded to one side of a vibration plate. This unimorph structure allows the device to adapt to temperature and shape challenges and enables it to provide a clear response while operating at low voltages. The actuator can be controlled with voltages as low as 24 V and can produce various vibration patterns depending on the amplitude and frequency of the applied voltage. With a frequency of 200 Hz and a peak voltage of 24 V, the actuator offers a typical displacement of 65 μm (no load).
TDK's ultra-thin PiezoHapt actuator is now available from Mouser Electronics in an 80 × 60 mm vibration plate and represents an ideal energy-saving haptic solution. Providing a wide range of vibration patterns, the PiezoHapt is ideal for haptic feedback applications in devices such as smartphones, wearables, tablets, touchscreens, and industrial controls.
