Film heaters

Film heaters using Canatu CNT provide clear field of vision for ADAS systems to function in any weather.



Canatu carbon nanotubes (CNTs) are uniquely suited for demanding heating applications. Canatu produces nanoscale carbon networks on a variety of thin film substrates to form an extremely thin heating layer. These film heaters can be further customized to suit various customer specifications.

Canatu film heater benefits:

  • fast-acting and power-efficient
  • even heating
  • high transparency and superior optical performance
  • high robustness for harsh environmental conditions
  • high level of integration flexibility

Fast, efficient and even heating

Canatu film heaters are made from a nanoscale CNT layer that has been evenly distributed across the heating surface. This even coating results in efficient and even heating, minimizing any thermal gradients across the surface.

Superior optical performance

Canatu film heaters exhibit high optical transparency. Further, they have minimal haze, low distortion and preserve waveform uniformity in laser applications. Canatu film heaters thus provide an optimal solution for applications requiring high level of optical performance.

Meeting the rigid reliability standards

With autonomous cars on the rise, safety and reliability standards in the automotive industry are more rigid than ever. In light of this, Canatu film heaters have undergone rigorous testing to earn 3rd party validation in these aspects, passing several rigorous test procedures. This is in line with Canatu’s commitment to R&D, which has allowed the company to consistently improve upon its products and solutions.

“We are extremely happy that Canatu’s heater product has achieved the high industry standards for reliability. We have set rigid quality standards for our suppliers in accordance with customer needs. High evidence of reliability is required to ensure products will always work,”

Toshihiko Muraki, Senior Director, Thermal Systems Business Group at DENSO CORPORATION

These standards ultimately vary between markets, with Japanese benchmarks being universally recognized as most stringent. Thus, meeting reliability requirements in Japan signifies that Canatu will likely be able to comply and supersede other international standards.

Raising performance levels and lowering costs

Canatu has been mass manufacturing for automotive applications since 2015. Since then, Canatu has moved towards effectively industrializing CNT film by more than doubling previous performance levels whilst also lowering costs.

Years of R&D has resulted in a record-breaking industrially applicable sheet resistance to optical transparency ratio in CNT films at 35Ω/sq to 90% transmittance. Though increasing electrical conductivity without harming transmittance or adding cost is a significant challenge, these constraints were mitigated due to Canatu’s wealth of nanotechnology expertise. Canatu’s careful control over the synthesis process produces longer CNTs that are extremely clean, enabling the formation of thin yet strong CNT networks.

Furthermore, Canatu’s scalable product platforms provide a solid core for applying Canatu CNT for various industries. Production costs have decreased ten-fold in the past three years, with the downward trend projected to continue.

ADAS LiDAR heaters
