![]() Instead, you want to provide the user with localized, bodily sensations and tactile effects exactly where – and when – it matters. The key is to embed localized, HD haptic technology that doesn’t shake the entire device. In fact, it referenced that the global haptic component market will be worth $4.8 billion by 2030! Thin, light, flexible piezo actuators ARE the way of the future, providing consumers with new levels of “near touch” interactivity and engagement with their devices. The mounting position does not necessarily have to be centered at the device.I recently read an interesting article about the latest detection solution that uses localized haptics to replace the button on smart phones – it’s fantastic to see the increasing adoption of haptic technology for these types of applications. ![]() The actuator / booster block (schematically illustrated below, length about 6 cm) has to be attached tightly onto the device which has to be vibrated - ideally on the rear side- by screwing or gluing. A proper electrical driving of the piezo actuator.An efficient mechanical implementation of the piezo actuator(s) into the HMI.How to Implement Haptivity ® into your Device? Key Points With a suitable mechanical device this piezo shrinkage is converted into a lateral movement which is coupled into the touch surface. According to the piezo-electric effect, the piezo(s) change the geometry. In certain configurations this can be the actuator piezo itself (by utilizing the reverse piezo-electric effect of the actuator functionality), but in general it should be a separate pressure sensing component.Īfter a pressure threshold has been exceeded (which is detected from the implemented controller), a single sine half wave of ~30 V is applied to the actuator piezos. Therefore, the device must comprise a component that is able to measure the applied pressure. It is absolutely essential to generate a distinctive surface vibration only after the operator has exceeded a certain pressure threshold – similar to a mechanical button. In order to simulate a mechanical button it is not sufficient to apply just a vibration to the surface that has been touched from the operator. Common structure for uni-morph and bi-morph, therefore A-A' and B-B' are different.The number of layer lamination is shown as "8 layers," which is a typical example.The technology is covered by more than 100 Kyocera patents.Various design elements as sliders or rotators can be realized.Haptic parameters of the simulated button (the subjectively perceived „click“) are controlled by S/W and are widely adjustable only by S/W.The actual mechanical movement of the touch surface is 50-80µm.In certain configurations the actuators can also be used as pressure sensors. ![]() Actuators are multilayer piezos with very small construction space requirements (60 mm x 10 mm x 10 mm). ![]() ![]() Simulation of a mechanical button on any surface (touchpad / touchscreen).Outstanding Features of Kyocera’s Haptivity ® Technology The implementation of haptics into industrial displays is challenging since there are specific requirements regarding dust- and waterproofness. Haptics are not only requested for use cases with the incorporation of a display, but also for the replacement of singular mechanical switches or even complete keyboards. The industrial HMI market is asking for haptic solutions for about 2 to 3 years, similar to the automotive HMI market.Ĭurrently, for the industrial market there is no solution under mass production. So far, haptic feedback systems used in the automotive market are all based on magnetic solutions – with respective drawbacks like constructions space, slow response and limited functionality. The automotive industry would like to make the overall interior smoother and more homogeneous – and consequently replace mechanical switches but would like to keep the haptic feedback of those switches the driver is used to. The operation of automotive T/Ps without haptic feedback does not offer a „fool proof“ operation and is consequently distracting the driver as the input has to be verified with different senses. The automotive market is asking for haptic solutions for about 2 to 3 years. Haptivity ® is Kyocera’s virtual reality technology that allows the simulation of a mechanical knob and further haptic effects on any surface. ![]()
