Printed Haptic Surfaces That Let Drivers Feel Touchscreen Buttons Without Looking

manufacturingTestedTRL 5

You know how car dashboards are switching from physical buttons to flat touchscreens? The problem is you have to look down to tap the right spot — dangerous while driving. This project figured out how to print tiny vibrating actuators onto thin plastic films, then mold them right into the dashboard surface. The result is a touchscreen that pushes back — you can feel roughness, vibrations, and raised edges under your fingertips, just like real buttons, without ever taking your eyes off the road.

The business problem

What needed solving

Car dashboards are going all-touchscreen, but flat glass and plastic surfaces give zero tactile feedback. Drivers have to look away from the road to find and press virtual buttons — creating a real safety problem. The industry needs a way to make smooth surfaces feel like they have physical buttons, without adding bulk or mechanical parts.

The solution

What was built

The team built a small-scale dashboard prototype with printed Electro-Active Polymer actuators on plastic foils, integrated through injection molding. They delivered a working electronic demo board with full documentation, custom drive electronics, and software libraries that let the surface reproduce roughness, vibration, and relief sensations. The prototype was tested with real end-users.

Automotive OEM & Tier-1 Suppliers
enterprise
Target: Dashboard and cockpit module manufacturers

If you are an automotive interior supplier dealing with the shift from physical buttons to flat touchscreens — and the driver-safety complaints that come with it — this project developed printed haptic films using Electro-Active Polymers that integrate directly into injection-molded plastic dashboards. The small-scale prototype was demonstrated with end-users and evaluated for roughness, vibration, and relief sensations. With 5 industry partners already in the consortium, the manufacturing route from lab to production line is mapped out.

Consumer Electronics
mid-size
Target: Manufacturers of smart appliances, wearables, or home automation panels

If you are a consumer electronics company looking for ways to add tactile feedback to flat plastic surfaces — think washing machine panels, smart home controllers, or appliance fronts — this project built a conformable haptic surface using large-area printing on plastic foils. The technology was tested with real users and comes with software libraries for reproducing accepted sensations like roughness and vibration. The printing-based manufacturing is designed to be cost-effective at scale.

Industrial Equipment & Machinery
any
Target: HMI and control panel manufacturers for factory or medical equipment

If you are an industrial HMI manufacturer struggling with the trade-off between sleek flat-panel designs and the tactile confirmation operators need in safety-critical environments — this project developed a thin organic electronic layer that adds haptic feedback to any molded plastic surface. The consortium of 10 partners across 5 countries delivered a working prototype with custom electronics driving both sensors and actuators, accessible through software libraries.

Frequently asked

Quick answers

What would it cost to integrate this haptic technology into our product?

The project focused on large-area, cost-effective printing technologies specifically to keep manufacturing costs down. However, no per-unit pricing data is available from the project outputs. With EUR 3,774,006 in EU funding across 10 partners, significant R&D groundwork has been done — licensing or co-development would leverage that investment.

Can this be manufactured at industrial scale?

The technology was specifically designed for large-area printing on plastic foils and integration via standard plastic molding injection. These are established industrial processes. However, the project demonstrated a small-scale prototype, so scaling to full production volumes would require further engineering and tooling work.

What is the IP situation and how can we license this?

The project was a Research and Innovation Action (RIA) funded under Horizon 2020, with IP typically shared among consortium members according to their grant agreement. The coordinator is CEA (French Atomic Energy Commission), a major public research body. Licensing discussions would need to go through the relevant consortium partners who contributed to the specific components you need.

How mature is this technology — is it ready to put in a product?

The consortium built and tested a small-scale dashboard prototype with end-users, evaluating haptic sensations like roughness, vibration, and relief. The electronic demo board with full documentation was delivered. This puts the technology at roughly TRL 5 — validated in a relevant environment but not yet production-ready.

What specific haptic effects can this surface produce?

Based on the project objective, the technology reproduces three distinct tactile sensations: roughness, vibration, and relief (raised features). These are driven by Electro-Active Polymer actuators arranged in a matrix on plastic foils, controlled through custom electronics and accessible via software libraries.

Does this meet automotive safety and regulatory standards?

The project was motivated specifically by safety concerns around eyeless interaction during driving. End-user testing was performed on the small-scale prototype. However, based on available project data, formal automotive certification (e.g., ISO 26262 functional safety) is not documented in the deliverables.

Who built this and can they support integration?

The consortium includes 10 partners from 5 countries (DE, EL, ES, FR, UK) with 5 industry partners and 3 SMEs — covering the full value chain from materials to technology manufacturing to OEM integration. The coordinator is CEA in France, one of Europe's largest research organizations with extensive technology transfer experience.

Consortium

Who built it

This is a well-balanced consortium with real commercial intent. Out of 10 partners across 5 countries, half are industry players (5 companies including 3 SMEs), which means the technology was developed with manufacturing and market realities in mind — not just academic curiosity. The coordinator, CEA in France, is one of Europe's top applied-research organizations with a strong track record in technology transfer. The presence of 2 universities and 3 research centers provides the scientific backbone, while the industry partners — covering materials, manufacturing technology, and OEM integration — represent the full value chain needed to bring haptic surfaces from lab to production. For a business looking to adopt this technology, the consortium structure means there are multiple potential licensing or co-development partners depending on which part of the technology stack you need.
