“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.

Tesla grabs massive Las Vegas warehouse for interesting Cybercab project
Tesla quietly filed plans to build the Cybercab car wash, and on May 12, the company submitted a permit to begin renovating the “Tesla Center Cybercab Phase 2 Car Wash,” documents show.
Tesla is beginning to construct what will be an incredibly unique project, as it is now building a 36,000-square-foot car wash just for the Cybercab in Clark County, Nevada, near Las Vegas.
Tesla quietly filed plans to build the Cybercab car wash, and on May 12, the company submitted a permit to begin renovating the “Tesla Center Cybercab Phase 2 Car Wash,” documents show.
This is not just some ordinary car wash. Instead, it’s a dedicated, high-tech maintenance hub built specifically for Tesla’s ride-hailing vehicle and the many units that will be in the fleet.
According to the permit documents, which were first spotted by MarcoRP, a Supercharger observer on X, the work involves upgrading and updating the interior and exterior of an existing 36,000-square-foot facility. Crews will construct a full car-wash enclosure, relocate tire-service equipment, and install new power raceways.
Tesla has reportedly submitted plans for a carwash dedicated for Robotaxis in Las Vegas. The permit, filed with Clark County on May 12th, describes “Tesla Center Cybercab Phase 2 Car Wash.”

Every camera on a Tesla Cybercab must stay clean, and without a human driver to perform manual maintenance on the vehicle, this Cybercab-specific car wash will be crucial in keeping the fleet operational, safe, and effective.
Tesla has spent years perfecting unsupervised FSD, and the Cybercab – unveiled last year as a driverless, two-seater purpose-built for ride-hailing – is the physical embodiment of that vision. Industry skeptics have long questioned how a massive Robotaxi network could scale without drivers handling basic upkeep.
Tesla just answered them with a permit filing. Sources close to the project suggest this could be the first of several such hubs, with whispers of similar plans already surfacing in Texas.
A purpose-built Robotaxi wash station means fleets can cycle vehicles through cleaning, charging, and minor servicing at lightning speed with almost no human intervention. Optimus robots could eventually handle the physical work, turning the entire operation into a lights-out, 24/7 machine.
Las Vegas, with its endless tourist traffic and wide-open roads, is the perfect proving ground. Imagine stepping out of a gleaming Cybercab after a night on the Strip, knowing the same vehicle will be sparkling clean and ready for the next rider within minutes.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
Critics who claimed Robotaxis would get filthy and unreliable now look shortsighted. However, it will be interesting to see how many of these types of facilities the company establishes, especially as it plans for the Robotaxi fleet to be available everywhere.
If the permit moves forward as expected, Las Vegas could witness the first large-scale, fully autonomous taxi operation complete with its own cleaning infrastructure. As soon as Tesla solves wireless charging, we’re looking at a very capable and potentially fully autonomous ride-sharing business from A to Z.

Tesla puts Giga Berlin in Plaid Mode with new massive investment
The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.
Tesla is pushing forward with significant upgrades at its Gigafactory Berlin-Brandenburg in Grünheide, Germany, signaling renewed confidence in its European operations despite past market challenges.
The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.
In April, plant manager André Thierig announced a 20 percent increase in Model Y production starting in July, following a record Q1 output of more than 61,000 vehicles. To support the ramp-up, Tesla plans to hire approximately 1,000 new employees beginning in May and convert 500 temporary workers to permanent positions.
The move is expected to lift weekly production significantly, addressing rebounding demand in Europe after a challenging 2025.

The expansion builds on earlier progress. In 2025, Tesla secured partial approvals to add roughly 2 million square feet of factory space, raising potential annual vehicle capacity from around 500,000 toward 800,000 units, with longer-term ambitions approaching one million vehicles per year. Logistical improvements, new infrastructure, and battery-related facilities are already underway on company-owned land.
Battery production is the latest major focus. On May 12, Thierig revealed an additional $250 million investment in the on-site cell factory. This more than doubles the planned 4680 battery cell capacity to 18 gigawatt-hours annually—up from the 8 GWh target set in December 2025—while creating over 1,500 new battery-related jobs.
Total cell investments at the site now exceed previous figures, bringing the factory closer to full vertical integration: cells, packs, and vehicles produced under one roof. Tesla describes this as unique in Europe and a step toward stronger supply chain resilience.
The plans come amid regulatory and community hurdles. Earlier expansion proposals faced protests over environmental concerns and water usage, leading to phased approvals beginning in 2024. Tesla has navigated these by emphasizing sustainable practices and economic benefits, including thousands of local jobs in Brandenburg.
With nearly 12,000 employees already on site and production steadily climbing, Gigafactory Berlin is poised for growth. The combined vehicle and battery expansions position the plant as a key hub for Tesla’s European ambitions, potentially making it one of the continent’s largest manufacturing complexes if local support continues.
As EV demand recovers, these investments underscore Tesla’s commitment to scaling efficiently in Germany while addressing regional supply chain needs.
