Smart and Flexible Sensor Solutions

PolyIC: Custom Sensor Solutions

Touch-free mobile devices, smart home devices, or vending HMI displays? Unthinkable today? Practical operation by gentle touch has become an integral part of our everyday life. Whether in the office or at home, touch screens, touch sliders, and touch wheels impress with their intuitive operation.

What mostly means convenience for the end user is important for product manufacturers for a completely different reason: Touch applications give you greater freedom in product design. By eliminating mechanical components such as switches, rotary wheels, or an entire keyboard, designers can adapt the variable size and format of their electrical device to customer requirements.

Be inspired by our flexible touch solutions and discover our range of sensor foils – Made in Germany.

And there are more features that will delight your customers:

  • Time-saving input and device control
  • Individual input screens possible (without restrictions due to mechanical control elements)
  • Space and weight savings
  • Price advantage as mechanical elements are eliminated
  • Hygienic advantage due to the easy-clean surface
  • No unwanted deposits in gaps between mechanical components
  • Possibility of atmospheric backlighting effects
  • Harmonious integration into the holistic design concept
  • Made in Germany

LEONHARD KURZ and PolyIC, together with MENTOR, present the ‘Rainbow Textile Demonstrator’

Fürth/Germany, May 27, 2025: LEONHARD KURZ, the world's leading supplier of innovative finishing solutions, together with its subsidiary PolyIC and MENTOR, the specialist for integrated lighting solutions, present a forward-looking cooperation project: The ‘Rainbow Textile Demonstrator.’ The technology will be presented to the general public at the Folien + Fahrzeug trade fair in June 2025 and opens up a new dimension for vehicle interior design.

 

Textile innovation with design power and functionality

The Rainbow Textile Demonstrator represents a new generation of functional, design-oriented textiles for vehicle interiors. MENTOR developed the luminous woven fibers in collaboration with its subsidiary MUNDA. The resulting textile lighting systems are being combined for the first time in this project with transparent, flexible touch sensors from KURZ subsidiary PolyIC - a technological milestone.

The project focuses on combining highly developed, light-conducting fiber technology with surface material from MENTOR and transparent, flexible sensor technology from PolyIC. MENTOR uses extremely thin, malleable light guides woven into textiles, which are already being used successfully in the automotive industry, for example in the Audi A3. “The luminous textiles used as surface lighting are unique in the industry to date. With additional sensor technology for individual brightness control and color change for individual fields, the demonstrator shows what will be possible in the future,” explains Dr. Markus Höner, Head of Development at MENTOR.

 

Touch function and dynamic lighting effects for automotive interiors

The highlight of the joint development is the integration of transparent capacitive PolyTC® sensors from PolyIC. These sensors are completely embedded in the textile fabric, remaining invisible and flexible – and still enable precise touch operation. This allows color changes, brightness gradients and animated rainbow effects to be controlled precisely – in line with adaptive, interactive vehicle design. “The sensor technology is touch-sensitive through the textile and can be customized using software. This opens up completely new design freedoms for vehicle manufacturers – from gently backlit door panels to animated lighting elements in the vehicle interior,” reports Dr. Wolfgang Clemens, Director of Product Management & Business Development at PolyIC.

 

Partnership-based technology transfer for sustainable innovation

LEONHARD KURZ and PolyIC are providing the ideal basis for innovative mobility solutions with their expertise in functional surfaces and smart sensor technology, as well as their resource-saving decoration technologies. Together with MENTOR, an established Tier 1 supplier of OEM lighting solutions, they are creating a textile platform that can be integrated into new interior concepts in terms of both function and design.

In addition to its design benefits, the demonstrator also contributes to sustainability: Thin textile substrates, simple integration, no additional brackets or complex assembly – all of which save resources, weight, and production costs.

 

Experience innovation live!

The Rainbow Textile Demonstrator will be presented at the Folien + Fahrzeug trade fair at the LEONHARD KURZ booth. Visitors will be able to experience the various lighting scenarios, touch functions, and design options live.
