0.35mm thin haptic actuator operates at up to 200Hz

February 14, 2017 // By Julien Happich
TDK has expanded its portfolio of haptic components with a 0.35mm thin PiezoHapt actuator featuring a response time of just 4ms.

PiezoHapt has a unimorph design consisting of a multilayer piezo element bonded to one side of a vibration plate. Much thinner than conventional eccentric rotary motors and linear resonant actuators, the device can be driven with low voltages under 24V 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 80x60mm (vibration plate). At a frequency of 200Hz (sine-wave) and a voltage of 24V peak, the component offers a typical displacement of 55µm. PiezoHapt is suitable for providing haptic feedback to user actions in the displays of smartphones and tablets.
