Mini haptic feedback actuators shrink dimensions

June 11, 2019  Stephen Law

TDK PowerHap 0904H014V060 and 1204H018V060 miniature rectangular piezo actuators for haptic feedback have smaller dimensions of 9 x 3.75 x 1.4mm and 12 x 4 x 1.8mm, respectively. At the maximum operating voltage of 60V, devices can accelerate a mass of 100 grams at 3.3 g(pk) or 5 g (pk) with maximum displacements of 15 µm or 27µm, respectively. Devices deliver high acceleration and large forces in a very compact design, coupled with a short response time of less than one millisecond. Devices deliver low energy consumption of 0.35mJ or 0.6mJ per feedback. Devices provide strong sensing functionality by using the inverse piezo effect.
