Solutions for Haptics
To generate vibrotactile haptic feedback on surfaces, e.g. on displays or for wearable devices, actuators are required. Many of todays solutions make use of electromagnetic actuators which often limits the haptic feedback to simple clicks or boring vibrations. To generate more versatile haptic feed back, so called high definition haptics, a new generation of actuators is required.
Piezoelectric actuators are perfect to create high definition haptics. This is mainly because of their short response time and large bandwidth. Moreover piezo actuators come in a compact package combined with low power consumption and strong force.
TDK offers two different product lines, specifically designed for haptic feedback:
