Development of self-healing lens material to prevent traffic accidents in self-driving cars
– Preventing distortion of autonomous vehicle sensor signals by removing scratches in 60 seconds with sunlight – Published in the January issue of ACS Applied Materials & Interfaces
Newswise — Safety issues of self-driving cars have emerged due to frequent self-driving traffic accidents. A self-healing lens material that can prevent car accidents that occur due to signal distortion by restoring scratches on the sensor surface of the self-driving car has been developed.
The Korea Research Institute of Chemical Technology (KRICT, President Lee, Young Kuk) research team led by Dr. Kim Jin Chul, Park Young Il, and Jeong Ji-Eun* and Prof. Kim Hak-Rin and Prof. Cheong In Woo in Kyungpook National University (KNU) developed a material that heals scratches on the sensor of an autonomous vehicle.
* Technology from「Can scratches on car surfaces disappear when exposed to sunlight? : A new self-healing coating material」, published in 2022, has been further developed to enable not only structural recovery but also functional recovery such as recovery of an optical signal.
When this self-healing optical material is used in the sensor of an autonomous vehicle, it is expected that the life expectancy of the product can be increased and future technology that can prevent malfunctions due to surface damage can be secured.
A lens is a tool that collects or disperses light and is used in many everyday optical devices such as cameras, cell phones, and glasses. However, if the lens surface is damaged by a scratch, the image or optical signal received by the optical device can be severely distorted.
Recently, traffic accidents caused by recognition errors and malfunctions of vision systems* such as LiDAR sensors and image sensors of self-driving cars have repeatedly occurred. As a result, confidence in the safety of self-driving cars is rather low**.
* LIDAR sensors and image sensors that acts as the ‘eyes’ of an autonomous vehicle
** The results of a survey by the American Automobile Association showed that the number of respondents who were afraid of using self-driving cars increased by 13% from 55% in 2022 to 68% in 2023.
The KRICT-KNU joint research team developed a transparent lens material that can remove scratches on the sensor surface within 60 seconds when focused sunlight is irradiated using a simple tool such as a magnifying glass.
Because self-healing is favorable when molecular movement within the polymer is free, flexible materials are generally advantageous in securing excellent self-healing performance. However, lenses or protecting coating materials are made of hard materials, and thus it is very difficult to impart a self-healing function. To solve this problem, the research team combined a thiourethane structure, which is already being used as a lens material, and a transparent photothermal dye* to design a ‘dynamic chemical bond’ in which the polymers repeat disassembly and recombination under irradiation of sunlight.
* A dye that converts light energy into heat energy
In particular, the developed transparent organic photothermal dye can selectively absorb light of a specific near-infrared wavelength (850-1050 nm) without interfering with the visible light region (350-850 nm) used for image sensors and the near-infrared region (~1550 nm) used for LiDAR sensors.
When sunlight is absorbed by photothermal dyes, the surface temperature of the developed lens material rises as the light energy is converted into thermal energy. Subsequently, the increased surface temperature makes it possible to self-heal a surface scratch by repeating the dissociation and recombination of chemical bonds in the polythiourethane structure.
The developed lens material shows perfect self-healing even when scratches cross each other, and provides excellent resilience, maintaining 100% of the self-healing efficiency even if the process of scratching and healing at the same location is repeated more than five times.
Dr. Lee Young Kuk, president of KRICT, said, “This technology is a platform technology that synthesizes self-healing lens materials using both an inexpensive high-refractive polymer material and a photothermal dye. It is expected to be widely used in various applications such as autonomous vehicle sensors as well as glasses and cameras.”

Driving Habits May Cost More Than You Think: Data-Backed Driving Techniques to Reduce Fuel Costs and Vehicle Wear
Rising Fuel Costs
(Feature Impact) If you’re feeling pain at the pump, you’re not alone. However, it’s not just rising gas prices that can impact your wallet – it might be your own habits on the road that negatively impact fuel efficiency and add extra strain to your vehicle.
With gas prices fluctuating by more than $1 per gallon nationally in recent years, Mercury Insurance is highlighting how driver behavior can significantly influence fuel costs.
According to the U.S. Department of Energy, aggressive driving – rapid acceleration and hard braking – can reduce fuel economy by up to 40% in city driving and 30% on highways, increasing annual fuel expenses by hundreds of dollars.
For the average American driver, that inefficiency adds up quickly. AAA estimates that annual fuel costs can exceed $2,000 depending on vehicle type and region. A 30-40% reduction in fuel economy can translate into hundreds of dollars in additional fuel expenses each year – before factoring in the added wear on key vehicle components.
“Most drivers think of aggressive driving as a safety issue, but it’s also a cost issue,” said John Dicken, director, material damage claims at Mercury Insurance. “From a claims standpoint, we see how habits like hard braking and rapid acceleration accelerate wear on brakes, tires and suspension components. Smoother driving isn’t just more efficient – it helps reduce preventable damage over time.”
The Hidden Cost of Driving Aggressively
Fuel is only part of the equation.
- Brake replacement can range from $300-800 per axle, depending on the vehicle.
- A new set of tires can cost $600-1,200 or more.
- Poorly maintained or underinflated tires can lower gas mileage by roughly 0.2% for every 1 PSI drop in pressure, according to federal transportation data.
Over time, inconsistent maintenance and aggressive driving habits compound these costs.
“Driving behavior directly impacts how often certain parts need to be replaced,” Dicken said. “When drivers anticipate traffic, maintain steady speeds and keep up with routine maintenance, they reduce strain on their vehicle and potentially avoid unnecessary repair expenses.”
Practical Eco-Driving Tips That Make a Measurable Difference
Consider these strategies recommended by Mercury Insurance to improve efficiency and reduce vehicle wear:
Accelerate gradually: Avoid rapid starts and jackrabbit acceleration, which significantly reduce fuel economy.
Brake smoothly and anticipate stops: Looking ahead and easing into stops reduces stress on brake systems.
Maintain consistent speeds: Using cruise control on highways can help improve fuel efficiency.
Keep tires properly inflated: Check tire pressure monthly and before long trips. If you’re unsure what your vehicle’s tires should be inflated to, locate the sticker inside the driver’s side door jamb for the proper PSI inflation or refer to the owner’s manual.
Remove excess weight: Extra cargo and unused roof racks reduce efficiency and increase drag.
Efficiency, Safety and Sustainability
The Environmental Protection Agency reports that transportation accounts for roughly 28% of total U.S. greenhouse gas emissions. While vehicle technology continues to improve, individual driving behavior remains one of the most immediate ways drivers can reduce both fuel consumption and environmental impact.
“Small, consistent changes in how we drive can produce meaningful savings over time,” Dicken said. “It’s one of the simplest ways drivers can protect both their budget and their investment.”

Jay Leno Test Drives the Slate Truck as Startup Pushes Toward 2026 Launch
The affordable electric pickup from Slate Auto is gaining attention after Jay Leno test drove the prototype on Jay Leno’s Garage. Here’s the latest update on pricing, features, reservations, and the planned 2026 production launch.
Testing the Slate Truck
The affordable electric pickup from Slate Auto is continuing to gain attention as the startup moves closer to production. One of the most visible recent developments came when legendary car collector and TV host Jay Leno featured the truck on his popular YouTube series Jay Leno’s Garage.
The episode offered one of the most detailed looks yet at the upcoming Slate Truck, including a real-world test drive, design insights, and a closer look at the company’s philosophy behind building what could become one of America’s most affordable electric vehicles.
Watch the Jay Leno Test Drive
What Jay Leno Revealed About the Slate Truck
During the episode, Leno drove a pre-production prototype of the truck while engineers from Slate Auto explained the design approach.
Unlike many modern EVs packed with luxury features, the Slate Truck is intentionally simple.
Key highlights from the test drive include:
A Focus on Simplicity and Repairability
One of the most notable ideas behind the truck is that it is designed to be easy to repair and modify. Instead of relying on proprietary parts or complex electronics, the vehicle uses a more straightforward architecture that could allow owners or independent mechanics to work on it.
This approach contrasts with many EVs that require dealership service or specialized tools.
Modular Body Panels and Customization
The Slate Truck is built around a modular platform with removable exterior panels and optional accessory kits.
According to the company, owners will be able to customize the vehicle with:
Different body panel styles Accessory racks and cargo options A potential conversion kit that can transform the pickup into a small SUV
The idea is to allow the vehicle to evolve with the owner’s needs over time.
Minimalist Interior
Inside the prototype shown to Leno, the truck features a very basic interior layout.
Instead of a large infotainment system, the vehicle relies heavily on smartphone integration and simpler controls to keep costs down. This minimalist philosophy is part of the company’s effort to build a lower-cost EV.
Pricing and the “Affordable EV” Promise
When the truck was first revealed in 2025, Slate Auto suggested the vehicle could cost under $20,000 after incentives.
However, with changes to federal EV incentives and updated pricing expectations, analysts now estimate the truck will likely start around the mid-$20,000 range.
Even at that price, the vehicle could still become one of the most affordable electric trucks available in the United States.
Production Plans in Indiana
The company plans to manufacture the truck in Warsaw, Indiana, where a large former industrial facility is being converted into an EV factory.
Production targets include:
Production start: Late 2026 Early deliveries: Possibly 2027 Potential capacity: Up to about 150,000 vehicles per year once fully ramped
Strong early interest has also been reported, with more than 100,000 reservations placed for the truck shortly after its reveal.
A Different Kind of Electric Truck
The Slate Truck is entering a market where most electric pickups—such as the Ford F-150 Lightning and Rivian R1T—sit at much higher price points.
Rather than competing on luxury or performance, the Slate Truck is aiming to fill a different niche: a practical, customizable, and relatively affordable electric work vehicle.
If the company can deliver on its promises, it could open the door to a new category of budget-friendly EVs.
For now, the test drive on Jay Leno’s Garage provides one of the clearest glimpses yet at how the truck might perform in the real world.
