Piezo haptics make a flat screen or touch control vibrate locally when a driver presses it, adding a tactile response without a conventional moving button. Automotive suppliers now describe components and production-oriented integrations—including a named NIO ET9 installation—but the evidence does not establish widespread adoption or prove that haptics reduce crashes or eyes-off-road time.
How piezo haptics work in a car
A piezoelectric actuator changes shape when electrical voltage is applied. When it is mechanically coupled to a display or control surface, that small movement becomes a brief vibration the user can feel. Thin actuators can fit into space-constrained locations; TDK describes its PowerHap actuators as suitable for placements including a steering column and as capable of rapid startup and clear tactile responses (TDK’s cockpit overview).
In a typical interaction, the system detects a press, waits for a configured pressure threshold, and drives the actuator to create the feedback. Kyocera describes HAPTIVITY® implementations in which pressure sensing triggers a short electrical drive; mechanical design converts actuator movement into lateral motion at the touch surface (Kyocera’s HAPTIVITY® description). Some configurations use the piezo element for pressure sensing; others use a separate sensor.
The actuator alone does not determine what the driver feels. The experience depends on the sensing method, driver electronics, the way the actuator is attached to the surface, control software and calibration. Kyocera identifies both mechanical implementation and electrical driving as important design considerations.

Where automotive piezo haptics are being used
Supplier evidence spans commercial components, development activity, research demonstrators and announced vehicle integrations. Those are different levels of maturity: a component designed for automotive use is not the same as a production fitment, and a research demonstration does not establish that a design is ready for a vehicle program.
| Example | What the source says | What it establishes |
|---|---|---|
| NIO ET9 center-console TUI Bar | On April 15, 2025, Boréas announced that its automotive haptic module had been integrated into the NIO ET9 center-console TUI Bar. Boréas called it the first tech-luxury EV infotainment application of its kind (Boréas’s announcement). | A named vehicle integration announced by the supplier. The “first” description is Boréas’s claim, not an independently verified industry-wide finding. |
| UltraSense and Mobase touch bar | On October 27, 2025, the companies announced a production ramp for a solid-state infotainment touch bar shipping on a high-volume global SUV platform. They describe in-plane piezoelectric force sensing, localized haptics and capacitive touch (UltraSense and Mobase’s announcement). | A production-oriented touch-bar program. The announcement does not identify the automaker or vehicle model. |
| TDK PowerHap | TDK lists PowerHap 6005 for automotive displays and PowerHap 1313/1919 for buttons and modules, with examples including steering wheels and consoles (TDK’s cockpit overview). | Marketed component options and example applications; the page does not identify specific vehicle fitments. |
| Boréas BOS1211 | Boréas announced on May 15, 2024, that its BOS1211 piezo haptic driver had completed AEC-Q100 Grade 2 automotive qualification. The company describes possible uses including buttons and sliders in a central display and steering wheel (Boréas’s qualification announcement). | Automotive qualification for this component, not qualification of every system built around it or proof of a particular vehicle installation. |
| Kyocera HAPTIVITY® and CEA-Leti patches | Kyocera describes automotive HAPTIVITY® development and work combining the technology with TactoTek’s IMSE approach (Kyocera’s automotive page). CEA-Leti describes piezoelectric patches as a research and industrialization path for touch surfaces, including transportation dashboards and control displays (CEA-Leti’s overview). | Company development and research/industrialization examples, not evidence by themselves of production fitment. |
How to evaluate a piezo haptic control
For drivers, a satisfying tactile response depends on whether it is easy to notice and feels consistent when used. For engineers or vehicle buyers comparing systems, useful distinctions go beyond the actuator’s name or size:
Rank #2
- Keeps your Simagic P2000 Haptic Control Module firmly in place with no shifting
- IMPROVED CABLE MANAGEMENT – Organizes cables for a cleaner and more efficient setup
- PROTECTS YOUR EQUIPMENT – Prevents damage by keeping your Control Module off the floor
- SPACE-SAVING DESIGN – Reduces clutter and frees up valuable rig space
- DURABLE CONSTRUCTION – Built for long-term reliability in demanding sim racing environments
- Feedback and response: Consider the character of the sensation, its consistency across the control surface and how promptly it follows a press.
- Mechanical integration: The actuator must couple effectively to the screen or control; the mounting and surface construction shape the result.
- Sensing and control: Check whether pressure sensing is integrated into the piezo element or handled separately, and how the electronics and software trigger feedback.
- Automotive qualification: Confirm which component or system was qualified and to what standard. Qualification of a driver IC does not automatically qualify a complete vehicle interface.
- Demonstrated maturity: Distinguish research demonstrations, supplier development, marketed components and announced production vehicle integrations.
Piezo is not automatically superior to electromagnetic haptics such as linear resonant actuators. Boréas says its technology offers faster response and a broader frequency range than older LRA approaches (Boréas’s qualification announcement); that is a supplier comparison, not an independent head-to-head test.
Do piezo haptics make touchscreens safer?
Suppliers present tactile feedback as a way to make touch controls easier to recognize by fingertip, potentially reducing the need to look at them. That is an intended interaction benefit, not proof of a safety outcome. The sources cited here do not provide a controlled, independent automotive study showing that piezo haptics reduce crashes or quantify a reduction in eyes-off-road time.

The Haptics Industry Forum’s Recommended Practices for Haptics in Automotive, version 1.0 (2021), offers industry context for designing haptic systems. Its existence does not establish that a particular supplier’s design follows those practices.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can a driver add piezo haptics to an existing car?
These are vehicle-interface components and engineering evaluation resources, not consumer add-ons intended to retrofit a car. TDK offers PowerHap actuators and a development starter kit. Kyocera describes an evaluation kit with actuators and a driving system, with details available by contacting the company (Kyocera’s HAPTIVITY® page). Boréas’s BOS1211 is a driver IC, and its ET9 announcement concerns a supplier-level module integration. These options are relevant to engineers developing interfaces, rather than owners seeking a plug-in upgrade.
