New Piezo Actuators for Haptic Effects
TDK Corporation has added two new piezo actuators to its range of PowerHap piezo actuators for haptic feedback. The size of the 0904H014V060 actuator is 9 x 3.75 x 1.4 mm and the 1204H018V060 is 12 x 4 x 1.8 mm. At the maximum operating voltage of 60 V, they are able to accelerate a mass of 100 grams at 3.3 g (pk) or 5 g (pk) with maximum deflection of 15 µm or 27 µm, respectively.

The compact PowerHap actuators can achieve high acceleration rates and produce large forces while offering a response time of less than one millisecond. A key feature is the low energy consumption of only 0.35 mJ or 0.6 mJ per feedback event. By making use of the reverse-piezo effect they can also be used to sense physical stress.

The PowerHap actuators will typically be used in the design of smartphones, tablets, game consoles, household appliances, VR/AR equipment, digitizers and handheld medical devices.
