Advanced driver assistance systems (ADAS) are transforming the safety of cars by providing advanced safety features that help drivers navigate roads more safely. Moreover, ADAS technology will be the key to making self-driving cars a reality in the not-so-distant future. 

ADAS technologies rely heavily on cameras and sensors to detect road conditions, other vehicles, and obstacles. However, environmental factors like frost, ice, and condensation obscure sensor and camera visibility and accuracy, thus limiting their performance and compromising road safety.

CNTs Could Winter-Proof Car Sensors

However, emerging research has highlighted the potential of carbon nanotubes (CNTs) to address this problem by weather-proofing critical components. CNTs are excellent candidates for weather-proofing cameras and sensors due to their inherent properties: 

- High thermal and electrical conductivity: CNTs can rapidly conduct heat and electricity, making them effective for generating enough heat to prevent frost or ice formation with just a tiny amount of energy. 

- Transparent and lightweight: CNT coatings are ultra-thin and extremely light, which means they can be applied as transparent layers that do not interfere with drivers' ability to see the road.

- Durable: CNTs are highly durable and resistant to wear, meaning they can withstand harsh environmental conditions over time, especially important for cold climates.

Now, Denso and Canatu are collaborating to develop ultra-thin, transparent CNT films that will keep sensors and cameras free from moisture and thus prevent condensation, frost, and ice from obscuring these critical safety technologies. 

TrimTabs’ Take

We are super excited about the potential of CNTs to make our cars and roads safer and the possibility of making autonomous vehicles a reality in the future. The collaboration between Denso and Canatu marks an exciting step forward, and we can’t wait to see where this leads.
