Datasheet

The PiezoHapt ultra-thin actuator from TDK is in stock at Mouser Electronics. The PiezoHapt is one of the world's thinnest haptic components on the market. With a thickness of only 0.35mm and a very short response time of just 4milliseconds, the PiezoHapt is thinner and more energy efficient than conventional eccentric motors or linear resonance actuators.

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.
