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.”

Gas prices have a $5 tipping point: New research shows when Americans start looking at EVs
Gas prices have a $5 tipping point: New research shows when Americans start looking at EVs
(Tiffany Miller for Hyundai) There is a moment at the gas pump when the number staring back at you stops feeling routine.
You expect the total to land somewhere familiar. And then, one day, it doesn’t. Not dramatically higher. Just high enough to feel different. Enough to make you pause before tapping your card.
According to new research from Hyundai Motor America, that moment is not hypothetical. For more than a third of American drivers, it has already happened. And for many, once it does, something shifts that does not quite shift back.
For 42% of Americans, pulling up to a pump now brings frustration or outright dread. Most have made peace with the routine, even if 39% describe their gas spend as “frustrating but expected.”
The experience at the pump hasn’t changed. The emotional weight of it has.
Most drivers have a number in their head where the math shifts. For 23% of those surveyed, $5 per gallon is where they would seriously start considering alternatives to a gas-powered vehicle. Not everyone will be moved by price, and 29% say they would not consider alternatives based on gas costs at all. But for a meaningful share of Americans, the tipping point is specific. It is a number on a sign, and many have seen it before.
More than one-third of Americans surveyed say a recent fill-up has already prompted them to research electric vehicles, and 23% say it has happened more than once.
What comes next is rarely dramatic. Some compare models or brands. Some search online. Some find themselves on an automaker’s website, further along than they expected to be. Most do not act on this impulse right away. But for a growing number, the pump is where the question starts.
The shift is real but uneven. If gas prices rose significantly and stayed high, 46% of those surveyed say they would be likely to seriously research an EV. Yet most Americans are still somewhere between curious and committed.
The pitch for electric vehicles is simple. Never stop for gas again. Nearly half of Americans say they would absolutely take that deal.
The transition is not frictionless. Charging access and range anxiety remain the top concern for 28% of potential buyers, and simple comfort with the status quo runs just as deep.
The desire to leave the pump behind is real. So is everything standing in the way.
The move toward electric vehicles is often framed as a long-term decision made with spreadsheets and incentive calculators, but for many Americans, it begins somewhere smaller. A routine fuel stop. A number that lands differently. A moment of hesitation before the receipt prints.
Methodology
Hyundai Motor America commissioned Atomik Research to conduct an online survey of 1,000 adults throughout the United States. The margin of error is plus or minus 3 percentage points at a 95% confidence level. Fieldwork was conducted between April 3 and April 6, 2026.

Nissan’s New Strategy: Innovation Meets Consolidation in a Changing Auto Market
Nissan’s New Strategy: Nissan is reshaping its lineup with fewer models, more hybrid technology, and smarter vehicles. Here’s what’s staying, what’s changing, and what it means for drivers.
Nissan’s New Strategy
As the global auto industry pivots toward electrification and smarter technology, Nissan is taking a more measured approach—introducing new innovations while trimming its lineup to focus on core models that drive sales and long-term value.
🚗 A Leaner, More Focused Nissan
In recent years, Nissan has begun reshaping its global strategy, reducing the total number of models while strengthening key vehicles across major segments. The goal is clear: prioritize profitability, streamline production, and invest in technology where it matters most.
Rather than flooding the market with new nameplates, Nissan is concentrating on a smaller, more competitive lineup—particularly in high-demand categories like SUVs and crossovers.
🔋 Innovation Where It Counts
Hybrid Technology Takes Center Stage
One of Nissan’s most important developments is its e-POWER hybrid system, which is set to debut more broadly in the U.S., particularly in the next-generation Nissan Rogue.
Unlike traditional hybrids, e-POWER uses a gasoline engine solely to generate electricity, while the wheels are driven by an electric motor. The result is a driving experience that feels closer to an EV—without requiring a charging station.
This technology reflects a growing industry reality: while electric vehicles are expanding, hybrids are emerging as a practical bridge for many consumers.
EV Evolution, Not Explosion
Nissan isn’t abandoning electric vehicles—it’s refining its approach.
The iconic Nissan LEAF is expected to return in a redesigned, crossover-style format, aimed at improving range, comfort, and mainstream appeal. However, Nissan is avoiding an aggressive all-electric push in favor of a balanced portfolio that includes gas, hybrid, and EV options.
Smarter Vehicles Through AI
Another key pillar of Nissan’s future is AI-assisted driving technology. The company plans to integrate advanced driver assistance and semi-autonomous features into a majority of its vehicles over the next several years.
These systems are designed to enhance:
- Safety
- Driver awareness
- In-car connectivity
While less visible than a new engine or redesign, this shift could become one of Nissan’s most impactful long-term innovations.
🚙 The Core Lineup: What’s Staying
Nissan’s future lineup is built around a group of proven, high-demand models that continue to evolve with new technology and features.
SUVs and Crossovers (The Backbone)
- Nissan Kicks – Entry-level, affordable, and recently redesigned
- Nissan Rogue – The brand’s best-seller and innovation leader
- Nissan Pathfinder – Family-focused with growing tech upgrades
- Nissan Armada – Large SUV with premium and performance appeal
These vehicles form a complete SUV ladder, covering nearly every price point and lifestyle.
Sedans (Reduced but Relevant)
- Nissan Sentra – Recently updated and positioned as the primary sedan
- Nissan Altima – Still available, though its long-term future is less certain
As consumer demand shifts toward SUVs, Nissan is scaling back—but not eliminating—its sedan offerings.
Trucks and Performance Models
- Nissan Frontier – A key player in the midsize truck segment
- Nissan Titan – Still present, but facing stiff competition
- Nissan Z – A modern revival of Nissan’s performance heritage
- Nissan GT-R – Nearing the end of its lifecycle, with a successor anticipated
These models help maintain Nissan’s identity beyond everyday transportation.
⚠️ Models Being Phased Out or Reevaluated
Not every vehicle is making the cut.
- The Nissan Versa is being discontinued after 2025
- The Nissan Ariya is seeing strategy adjustments depending on market demand
- Some low-volume global models are being eliminated as part of a broader consolidation effort
This reflects a broader industry shift: automakers are prioritizing efficiency and profitability over sheer volume.
🔍 The Role of the Nissan Kicks
One standout in this transition is the Nissan Kicks, which represents Nissan’s practical, value-driven approach.
Recently redesigned, the Kicks offers:
- Modern infotainment and safety features
- Improved comfort and available all-wheel drive
- Strong fuel efficiency at an affordable price point
While it doesn’t showcase cutting-edge hybrid or EV technology, it plays a crucial role as an entry-level gateway into the Nissan brand.
🧭 Industry Context: Why This Shift Matters
Nissan’s strategy mirrors broader trends shaping the automotive industry:
- EV adoption is growing—but unevenly
- Hybrids are gaining traction as a transitional solution
- SUV demand continues to dominate global markets
- Cost control and profitability are now top priorities
By focusing on fewer, stronger models, Nissan aims to remain competitive in a rapidly evolving landscape.
🧾 Bottom Line
Nissan is not simply cutting models—it’s redefining its identity.
- ✔️ Investing in hybrid technology, AI, and core SUVs
- ✔️ Maintaining key sedans, trucks, and performance vehicles
- ❌ Eliminating underperforming and low-demand models
The result is a lineup that is leaner, more technologically advanced, and better aligned with today’s market demands.
