“Smart skin” can identify weaknesses in bridges and airplanes using laser scanner
Recent research results have demonstrated that two-dimensional, on-demand mapping of the accumulated strain on metal structures will soon be a reality thanks to an engineered “smart skin” that’s only a fraction of the width of a human hair. By utilizing the unique properties of single-walled carbon nanotubes, a two-layer film airbrushed onto surfaces of bridges, pipelines, and airplanes, among others, can be scanned to reveal weaknesses in near real-time. As a bonus, the technology is barely visible even on a transparent surface, making it that much more flexible as an application.
Stress-inducing events, along with regular wear and tear, can deform structures and machines, affecting their safety and operability. Mechanical strain on structural surfaces provides information on the condition of the materials such as damage location and severity. Existing conventional sensors are only able to measure strain in one point along one axis, but with the smart skin technology, strain detection in any direction or location will be possible.
How “Smart Skin” Technology is Used
In 2002, researchers discovered that single-wall carbon nanotubes fluoresce, i.e., glow brightly when stimulated by a light source. Later, the fluorescence was further found to change color when stretched. This optical property was then considered in the context of metal structures that are subject to strain, specifically to apply the property as a diagnostic tool. To obtain the fluorescent data, researchers applied the smart skin to a testing surface, irradiated the area with a small laser scanner, and captured the resulting nanotube color emissions with an infrared spectrometer. Finally, two-dimensional maps of the accumulated strain were generated with the results.
The primary researchers, Professors Satish Nagarajaiah and Bruce Weisman of Rice University in Texas, have published two scientific papers explaining the methods used for achieving this technology and the results of its proof-of-principle application. As described in the papers, aluminum bars with holes or notches in areas of potential stress were tested with the laser technique to demonstrate the full potential of their invention. The points measured were located 1 millimeter apart, but the researchers stated that the points could be located 20 times closer for even more accurate readings. Standard strain sensors have points located several millimeters apart.
What Are Carbon Nanotubes?
Carbon nanotubes (CNTs) are carbon molecules that have been structurally modified into cylinders, or rather, rolled up sheets of carbon atoms. There has been some evidence suggesting that CNTs can be formed via natural processes such as volcanic events. However, to really capitalize on their unique characteristics, production in a laboratory environment is much more efficient.
Several methods can be used for production, but the most widely used method for synthesizing CNTs is chemical vapor deposition (CVD). This process combines a catalyzing metal with a carbon-containing gas which are heated to approximately 1400 degrees Fahrenheit, triggering the carbon molecules to assemble and grow into nanotubes. The resulting formation resembles a forest or lawn grass, each trunk or blade averaging .43 nanometers in diameter. The length is dependent on variables such as the amount of time spent in the high heat environment.
Besides surface analysis, carbon nanotubes have proven invaluable in many research and commercial arenas, their luminescence being only one of many properties that can improve and enable other technologies. Their mechanical tensile strength is 400 times that of steel while only having one sixth the density, making them very lightweight. CNTs also have highly conductive electrical and thermal properties, are extremely resistant to corrosion, and can be filled with other nanomaterials. All of these advantages open up their applications to include solar cells, sensors, drug delivery, electronic devices and shielding, lithium-ion batteries, body armor, and perhaps even a space elevator, assuming significant advances overcome its hurdles.
Next Steps
The nanotube-laced smart skin is ready for scaling up into real-world applications, but its chosen industry may take time to adopt given the general resistance to change in a field with long-standing existing technology. While awaiting embrace in the arena it was primarily designed for, the smart skin has other potential uses in engineering research applications. Bruce Weisman, also the discoverer of CNT fluorescence, anticipates its advantages being used for testing the design of small-scaled structures and engines prior to deployment. Niche applications like these may be the primary entry point into the market for some time to come. In the meantime, the researchers plan to continue developing their strain reader to capture simultaneous readings from large surfaces.

Texas township wants The Boring Company to build it a Loop system
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge.”
The Woodlands Township, Texas, has formally entered The Boring Company’s tunneling sweepstakes.
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge,” which offers up to one mile of tunnel construction at no cost to a selected community.
The Woodlands’ proposal, dubbed “The Current,” features two parallel 12-foot-diameter tunnels beneath the Town Center corridor near The Waterway. Teslas would shuttle passengers between Waterway Square, Cynthia Woods Mitchell Pavilion, Town Green Park and nearby hotels during concerts and large-scale events, as noted in a Chron report.
Township officials framed the tunnel as a solution for the township’s traffic congestion issues. The Pavilion alone hosts more than 60 shows each year and can accommodate crowds of up to 16,500, often straining Lake Robbins Drive and surrounding intersections.
“We know we have traffic impacts and pedestrian movement challenges, especially in the Town Center area,” Chris Nunes, chief operating officer of The Woodlands Township, stated during the meeting.
“The Current” mirrors the Loop system operating beneath the Las Vegas Convention Center, where Tesla vehicles transport passengers through underground tunnels between venues and resorts.
The Boring Company issued its request for proposals (RFP) in mid-January, inviting cities and districts to pitch local uses for its tunneling technology. The Woodlands must submit its application by Feb. 23, though no timeline has been provided for when a winning community will be announced.
Nunes confirmed that the board has authorized a submission for “The Current’s” proposal, though he emphasized that the project is still in its preliminary stages.
“The Woodlands Township Board of Directors has authorized staff to submit an application to The Boring Company, which has issued an RFP for communities interested in leveraging their technology to address community challenges,” he said in a statement.
“The Board believes that an underground tunnel would provide a safe and efficient means to transport people to and from various high-use community amenities in our Town Center.”

Tesla Model Y wins 2026 Drive Car of the Year award in Australia
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall.
The Tesla Model Y has been named 2026 Drive Car of the Year overall winner, taking the top honor after being judged as the vehicle that “moves the game forward the most for Australian new car buyers.”
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall, but the vehicle’s Juniper update strengthened its case with new ownership benefits and expanded software capability.
Drive’s overall award compares category winners and looks at which model most significantly advances the local new car market. In 2026, judges pointed to the Model Y’s five-year warranty and the availability of Full Self-Driving (Supervised) as a monthly subscription as key differentiators.
Priced from AU$58,900 before on-road costs, the all-electric crossover SUV offers a lot of value compared to similarly sized petrol and hybrid rivals. The ability to access Tesla’s Supercharger network across Australia also reduces friction for buyers moving to EV ownership.
Owners can add FSD (Supervised) for AU$149 per month. While it still requires driver oversight, the system expands the vehicle’s advanced driver-assistance capabilities and reflects Tesla’s software-first approach.
“The default choice for a reason. The Tesla Model Y makes the transition to electric both effortless and rewarding,” Drive wrote.
The 2025 Model Y facelift also sharpened the vehicle’s exterior, highlighted by a distinctive rear light bar that gives the crossover SUV a more modern road presence.
Drive described the Model Y as a benchmark for combining practicality, efficiency and technology at an accessible price point. With eligibility for federal Fringe Benefit Tax exemptions through novated leasing, its value proposition has improved for numerous buyers.
For 2026, the Model Y’s combination of range efficiency, charging access and software capability proved decisive. Ultimately, the award all but cements the Model Y’s position as one of the most influential vehicles in Australia’s evolving new-car market today.

Elon Musk reiterates rapid Starship V3 timeline with next launch in sight
Musk shared the update in a brief post on X, writing, “Starship flies again next month.”
Elon Musk has confirmed that Starship will fly again next month, reiterating SpaceX’s aggressive timeline for the first launch of its Starship V3 rocket.
Musk shared the update in a brief post on X, writing, “Starship flies again next month.” The CEO’s post was accompanied by a video of Starship’s Super Heavy booster being successfully caught by a launch tower in Starbase, Texas.
The timeline is notable. In late January, Musk stated that Starship’s next flight, Flight 12, was expected in about six weeks. This placed the expected mission date sometime in March. That estimate aligned with SpaceX’s earlier statement that Starship’s 12th flight test “remains targeted for the first quarter of 2026.”
If the vehicle does indeed fly next month, it would mark the debut of Starship V3, the upgraded platform expected to feature the rocket’s new Raptor V3 engines.
Raptor V3 is designed to deliver significantly higher thrust than earlier versions while reducing cost and weight. Starship V3 itself is expected to be optimized for manufacturability, a critical step if SpaceX intends to scale production toward frequent launches for Starlink, lunar missions, and eventually Mars.
Starship V3 is widely viewed as the version that transitions the program from experimental testing to true operational scaling. Previous iterations have completed multiple integrated flight tests, with mixed outcomes but steady progress. Expectations are high that SpaceX is now working on Starship’s refinement.
An aggressive launch schedule supports several priorities at once. It advances Starlink’s next-generation satellite deployment, supports NASA’s lunar ambitions under Artemis, and keeps SpaceX on track for its longer-term Moon and Mars objectives.
