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.
