TDK Corporation has developed the "PiezoHapt? Actuator " with tactile feedback and will provide samples starting in March. The PiezoHapt actuator is a single-crystal structure vibration device consisting of a laminated piezoelectric element and a vibrating plate. It supports low-voltage driving and supports various vibration modes. Compared with the conventional eccentric rotating electric machine actuators and linear actuators (linear resonant actuators) used for vibration, this product has the world's thinnest level *1 thickness (about 0.35mm) and can be transiently reacted.
The piezoelectric element of this product is a laminated type, which can generate a larger displacement amount than a single-plate type component of the same thickness. Therefore, unlike the piezoelectric haptic feedback technology, which is generally required to have a high voltage environment, the PiezoHapt actuator can transmit vibration to the skin even under low voltage conditions of 24V or less. In addition, this product has the characteristics of instantaneous response according to piezoelectric characteristics, and rises immediately at about 0.004 seconds*2. Compared with eccentric rotating motor actuators, it can work under short-time energization, consumes less power, saves energy and saves energy. Moreover, when using an eccentric rotating motor actuator, the amplitude depends on the design, and the PiezoHapt actuator is free to change the amplitude and spacing by pulse control, so that various vibration modes can be expressed in detail.
With virtual reality (VR) as the head, tactile sensations such as the touch of the fingertips are expected to be further applied to various fields. The low-voltage-driven thin PiezoHapt actuator is a new actuator with tactile feedback after the high-acceleration and high-efficiency EPCOS brand PowerHapTM piezo actuators released in November 2016, and it also expands TDK's capabilities. Provides a range of cutting edge haptic feedback solutions. The PiezoHapt actuator can be used for a variety of applications where tactile feedback is required through vibration.
