TDK's PHUA8060-35A-33-000 ultra-thin PiezoHapt actuator features a short response time of just 4 ms. PiezoHapt has a unimorph design consisting of a multilayer piezo element bonded to one side of a vibration plate. With a thickness of a mere 0.35 mm, the haptic actuator is much thinner than conventional eccentric rotary motors and linear resonant actuators, and is one of the world's thinnest haptic devices. Thanks to its fast rise time, PiezoHapt represents a power-saving solution compared to conventional solutions.

The actuator can be driven with low voltages of ≤24 V and can produce a wide variety of vibration patterns, depending on the amplitude and frequency of the voltage applied. The PHUA8060-35A-33-000 type has a footprint of 80 mm x 60 mm (vibration plate). At a frequency of 200 Hz (sine-wave) and a voltage of 24 V peak, the component offers a typical displacement of 55 µm. PiezoHapt is an ideal component for providing haptic feedback to user actions in the displays of smartphones and tablets.
