At the maximum operating voltage of 60V, the new piezo actuators can accelerate a mass of 100 grams at 3.3 g (pk) or 5 g (pk) with maximum displacements of 15 µm or 27 µm, respectively. The devices draw only 0.35mJ or 0.6mJ per feedback while delivering high acceleration and large forces in a very compact design, coupled with a response time under one millisecond. In addition to its actuator properties, PowerHap also offers good sensing functionality by using the inverse piezo effect. Typical application areas for the new PowerHap actuators include smartphones and tablets, household appliances, game consoles, VR/AR equipment, digitizers and handheld medical devices.
