EPCOS / TDK PowerHap Piezo Actuators

TDK PowerHap Piezo Actuators with Haptic Feedback and integrated sensor functionality feature high acceleration, force, and response time. The components provide high-quality haptic feedback. These PowerHap actuators are compact and greatly enhance the sensory experience of human-machine interfaces (HMIs) by engaging the full range of human tactile sensitivity. The devices consist of multilayer piezo plates with copper inner electrodes, which allows the actuators to be driven with relatively low operating voltages up to 120V. Once activated, the piezo plates only expand minimally in the z-axis but, due to the constant volume of the piezo effect, contract simultaneously in both the x and y axes.

The PowerHap module employs cymbals on both sides of the plate as levers to amplify the contraction by a factor of 15 on the z-axis. The PowerHap is available in three types: a 4N type with a displacement of 35µm typically, a 5N type that creates a displacement of up to 100µm, and a 20N type that can create a displacement of more than 200µm. These devices can generate forces of up to 5N and 20N, even with their compact dimensions.

EPCOS also offers PowerHap Piezo Actuators with copper inner electrodes and titanium bows for displacement amplification. These devices feature large displacement, high acceleration, high force, fast response time, and integrated sensor functionality.
