A University of Houston professor has taking a huge step in advancing his game-changing stroke recovery tech.

Jose Luis Contreras-Vidal, the director of the UH BRAIN Center, recently published his work on a noninvasive brain-machine in a summer issue of the journal Sensors. InnovationMap first reported on Contreras-Vidal's technology in 2022, when it was being tested.

Contreras-Vidal's device uses a wireless, mobile dry-electrode headset placed on the scalp to convert electroencephalography (EEG) recordings (or measurements of electrical activity in different parts of the brain) to interface with a closed-loop brain–computer (BCI) and communicate with exoskeleton devices. Together, the technology triggers robotic movement based on the wearer's brain activity.

The technology has potential to boost cortical plasticity after a stroke, which can improve motor skills recovery.

According to a statement from UH, a patent is pending on Contreras-Vidal's BCI algorithm and the self-positioning dry electrode bracket used on the scalp. The technology has also now been validated and tested at the University of Houston.

Contreras-Vidal says the technology makes stroke recovery easier for the user and even possible at home.

“Most commercial EEG-based BCI systems are tethered to immobile processing hardware or require complex programming or set-up, making them difficult to deploy outside of the clinic or laboratory without technical assistance or extensive training," he says in a statement. "A portable and wireless BCI system is highly preferred so it can be used outside lab in clinical and non-clinical mobile applications at home, work, or play.”

Additionally, the technology uses off-the-shelf components and is adjustable to fit about 90 percent of the population, according to UH.

"Current commercial EEG amplifiers and BCI headsets are prohibitively expensive, lack interoperability, or fail to provide a high signal quality or closed-loop operation, which are vital for BCI applications,” Contreras-Vidal adds.

The development of this technology was originally funded in part by an $813,999 grant from the National Science Foundation’s Division of Translational Impacts. UH reports that about 795,000 people in the United States suffer from a stroke annually.

Other leaders in Houston’s medical industry have tapped into innovative ways to treat and rehabilitate stroke patients in recent years. Baylor St. Luke's Hospital began using AI to reduce the time it takes to treat patients who've suffered from a stroke in 2021.

Robotic device created at the University of Houston helps stroke patients to rehabilitate

next-gen recovery

Almost 800,000 people in the United States suffer from a stroke annually — and the affliction affects each patient differently. One University of Houston researcher has created a device that greatly improves the lives of patients whose stroke affected motor skills.

UH engineering professor Jose Luis Contreras-Vidal developed a next-generation robotic arm that can be controlled by the user's brainwaves. The portable device uses a brain-computer interface (BCI) developed by Contreras-Vidal. Stroke patient Oswald Reedus, 66, is the first person to use a device of this kind.

Reedus lost the use of his left arm following a stroke that also caused aphasia, or difficulty speaking. While he's been able to recover his ability to speak clearly, the new exoskeleton will help rehabilitate his arm.

When strapped into the noninvasive device, the user's brain activity is translated into motor commands to power upper-limb robotics. As patients like Reedus use the device, more data is collected to improve the experience.

“If I can pass along anything to help a stroke person’s life, I will do it. For me it’s my purpose in life now,” says Reedus in a news release from UH. His mother and younger brother both died of strokes, and Reedus is set on helping the device that can help other stroke patients recover.

Contreras-Vidal, a Hugh Roy and Lillie Cranz Cullen distinguished professor, has led his device from ideation to in-home use, like with Reedus, as well as clinical trials at TIRR Memorial Hermann. The project is funded in part from an $813,999 grant from the National Science Foundation’s newly created Division of Translational Impacts.

"Our project addresses a pressing need for accessible, safe, and effective stroke rehabilitation devices for in-clinic and at-home use for sustainable long-term therapy, a global market size expected to currently be $31 billion," Contreras-Vidal says in the release. "Unfortunately, current devices fail to engage the patients, are hard to match to their needs and capabilities, are costly to use and maintain, or are limited to clinical settings."

Dr. Gerard E. Francisco, chief medical officer and director of the Neuro Recovery Research Center at TIRR Memorial Hermann, is leading the clinical trials for the device. He's also chair and professor in the Department of Physical Medicine and Rehabilitation at McGovern Medical School at UTHealth Houston. He explains that TIRR's partnership with engineering schools such as the Cullen College of Engineering at UH and others around the nation is strategic.

“This is truly exciting because what we know now is there are so many ways we can induce neuroplasticity or how we can boost recovery,” says Francisco in the release. “That collaboration is going to give birth to many of these groundbreaking technologies and innovations we can offer our patients.”

Here are 3 breakthrough innovations coming out of research at Houston institutions

Research Roundup

Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research projects, we look into studies on robotics advancing stroke patient rehabilitation, the future of opioid-free surgery, and a breakthrough in recycling plastics.

The University of Houston's research on enhancing stroke rehabilitation

A researcher at the University of Houston has seen positive results on using his robotics on stroke survivors for rehabilitation. Jose Luis Contreras-Vidal, director of UH's Non-Invasive Brain Machine Interface Systems Laboratory, recently published the results of the clinical trial in the journal NeuroImage: Clinical.

The testing proved that most patients retained the benefits for at least two months after the therapy sessions ended, according to a press release from UH, and suggested even more potential in the long term. The study equipped stroke survivors who have limited movement in one arm with a computer program that captures brain activity to determine the subject's intentions and then works with a robotic device affixed to the affected arm, to move in response to those intentions.

"This is a novel way to measure what is going on in the brain in response to therapeutic intervention," says Dr. Gerard Francisco, professor and chair of physical medicine and rehabilitation at McGovern Medical School at The University of Texas Health Science Center at Houston and co-principal investigator, in the release.

"This study suggested that certain types of intervention, in this case using the upper robot, can trigger certain parts of brain to develop the intention to move," he continues. "In the future, this means we can augment existing therapy programs by paying more attention to the importance of engaging certain parts of the brain that can magnify the response to therapy."

The trial was funded by the National Institute of Neurological Disorders and Stroke and Mission Connect, part of the TIRR Foundation. Contreras-Vidal is working on a longer term project with a National Science Foundation grant in order to design a low-cost system that would allow people to continue the treatments at home.

"If we are able to send them home with a device, they can use it for life," he says in the release.

Baylor College of Medicine's work toward opioid-free surgery

In light of a national opioid crisis and more and more data demonstrating the negative effects of the drugs, a Baylor College of Medicine orthopedic surgeon has been working to offer opioid-free surgery recovery to his patients.

"Thanks to a number of refinements, we are now able to perform hip and knee replacements, ranging from straightforward to very complex cases, without patients requiring a single opioid pill," says Dr. Mohamad Halawi, associate professor and chief quality officer in the Joseph Barnhart Department of Orthopedic Surgery, in a press release.

"Pain is one of patients' greatest fears when undergoing surgery, understandably so," Halawi continues. "Today, most patients wake up from surgery very comfortable. Gone are the days of trying to catch up with severe pain. It was a vicious cycle with patients paying the price in terms of longer hospitalization, slower recovery and myriad adverse events."

Halawi explains that his work focuses on preventative measures ahead of pain occurring as well as cutting out opioids before surgery.

"Opioid-free surgery is the way of the future, and it has become a standard of care in my practice," he says. "The ability to provide safer and faster recovery to all patients regardless of their surgical complexity is gratifying. I want to make sure that pain is one less thing for patients to worry about during their recovery."

Rice University's breakthrough on recycling plastics

Houston scientists has found a new use for an otherwise useless byproduct that comes from recycling plastics. Rice University chemist James Tour has discovered that turbostratic graphene flakes can be produced from pyrolyzed plastic ash, and those flakes can then be added to other substances like films of polyvinyl alcohol that better resist water in packaging and cement paste and concrete, as well as strengthen the material.

"This work enhances the circular economy for plastics," Tour says in a press release. "So much plastic waste is subject to pyrolysis in an effort to convert it back to monomers and oils. The monomers are used in repolymerization to make new plastics, and the oils are used in a variety of other applications. But there is always a remaining 10% to 20% ash that's valueless and is generally sent to landfills.

Tour's research has appeared in the journal Carbon. The co-authors of the study include Rice graduate students Jacob Beckham, Weiyin Chen and Prabhas Hundi and postdoctoral researcher Duy Xuan Luong, and Shivaranjan Raghuraman and Rouzbeh Shahsavari of C-Crete Technologies. The National Science Foundation, the Air Force Office of Scientific Research and the Department of Energy supported the research.

"Recyclers do not turn large profits due to cheap oil prices, so only about 15% of all plastic gets recycled," said Rice graduate student Kevin Wyss, lead author of the study. "I wanted to combat both of these problems."

Report: Houston reclaims top 10 ranking among America's best cities

Houston has made a triumphant return to America's 10 best cities for 2026, certifying the city is a cornerstone of the country's growth and economic prosperity.

Houston ranks No. 9 nationwide in the annual "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy. Each year, the report ranks the relative qualities of livability, cultural "lovability," and economic prosperity in 393 American cities with metropolitan populations of 500,000 or more.

Dallas surpassed H-Town as the No. 8 best city in America, and the Lone Star State boasts a strong presence among the top 25. Austin and San Antonio, respectively, were named the 11th and 24th best American cities this year.

Previously, Houston was dubbed the 13th best American city in 2025, down from its No. 10 ranking in the 2024 report.

Rather than profiling each individual city like in past reports, the 2026 edition focuses on regional and state prosperity. Texas' economic dominance is second only to Florida's, and the state's growth is solidified by the Dallas-Houston-Austin "triangle," where each metro has its own distinct economic identity, but when combined "form one of the most formidable regional economies in the world."

"In our 2026 survey, Dallas ranks third nationally as the place Americans believe offers the best job opportunities, Austin fifth, and Houston seventh," the report's author wrote. "That concentration of perceived economic opportunity in a single state is unmatched, and the GDP data confirms it isn’t just perception."

After being named one of the best places to start a business or a career earlier in 2026, Houston has continued to punch above its weight with its success in tourism, education, and housing growth.

Overall, the report found a correlation between a city's population growth and its latest ranking, with bigger cities appearing higher up on the list. The top three best American cities — New York, Los Angeles, and Chicago — are coincidentally the three largest metros, while Dallas and Houston are the fourth and fifth largest but appear eighth and ninth on the list.

"Scale compounds at the large city level — more people generate more economic activity, more cultural infrastructure, more employer presence, which attracts more people," the report said.

The top 10 best cities in America for 2026 are:

  • No. 1 – New York
  • No. 2 – Los Angeles
  • No. 3 – Chicago
  • No. 4 – Miami
  • No. 5 – San Francisco
  • No. 6 – Seattle
  • No. 7 – Las Vegas
  • No. 8 – Dallas
  • No. 9 – Houston
  • No. 10 – Boston

New probe into Tesla after vehicle slams into Houston-area home at high speed

Tesla Talk

The top U.S. auto regulator opened an investigation Monday, June 22, after a Tesla using an automated driving feature slammed into a Texas home at high speed and killed a 76-year-old woman standing inside.

The National Highway Traffic Safety Administration said it's opening a special investigation into the Tesla Model 3 crash on Friday near Houston, a significant probe because the car was using technology that Elon Musk considers key to the company's future.

The Tesla CEO is rolling out robotaxis using automated software in several U.S. cities this year and plans to invite Tesla owners to put their cars into the fleet using the same system across the country.

The driver told the Harris County Sheriff's Office that he was using the technology, according to a police report on the crash, but it's not clear what role, if any, it played in the incident.

Tesla did not respond to a request for comment but the head of the company's artificial intelligence efforts suggested on social media later Monday that the self-driving feature was not to blame.

“In this case, the driver manually overrode self-driving by pressing the accelerator all the way to 100% of the accel pedal in this residential area,” wrote Ashok Elluswamy on X, the platform that is now part of Musk's rocket company, SpaceX. “They reached a speed of 73 mph during the crash, and had the accelerator pressed even after the crash.”

The police report noted that the driver was not drunk and is cooperating. It identified the woman killed as Martha Avila.

Video obtained by KHOU-TV shows the car traveling at top speed over the front lawn of a brick home in Katy, then ramming into a front room. The next shot shows the car encased in the home amid piles of crumbling plaster, split beams and bits of furniture.

The auto safety regulator, known as NHTSA, has launched several investigations into Tesla, including one late last year into 58 incidents in which Teslas reportedly violated traffic safety laws while using self-driving technology, leading to more than a dozen crashes and fires and nearly two dozen injuries.

A few months earlier, the NHTSA opened an investigation into why Tesla apparently had not been reporting crashes promptly as required.

As for special crash investigations, the NHTSA has opened 46 involving Teslas using self-driving or driver-assistance technology over the past decade, according to the agency's records. In more than a dozen of those crashes, at least one person — a driver, passenger or pedestrian — was killed.

Tesla stock fell sharply early last year as car sales plunged amid a boycott of Musk after he waded into politics, leading President Donald Trump's budget-cutting Department of Government Efficiency initiative and embracing European extremist candidates.

Musk has since shifted the Tesla story to one less about car sales and more about AI and robotaxis, and done so successfully. The stock is up 16% in the past year.

Intuitive Machines lands $1M grant to expand robotics operations

Expansion mode

Houston-based Intuitive Machines is expanding its operations around the country.

The space tech company—which has offices and labs in Texas, California, Arizona, Colorado and Maryland—announced that it has received a $1 million grant from Maryland Gov. Wes Moore through the state's Build Our Future Grant. The funding will go toward expanding Intuitive Machines’ Super Cislunar Robotics Assembly Building (Supa-CRAB) Mechanisms and Robotics Center of Excellence in Anne Arundel County.

The company will move into a 69,000-square-foot facility and build out additional lab and office space. It will also procure equipment that will allow for in-house Assembly, Integration and Test (AI&T) activities, according to a news release. Intuitive Machines says the expansion will take place this fall.

“This collaboration shows how industry, state programs, and education can reinforce one another,” Steve Altemus, CEO of Intuitive Machines, said in the release. “Maryland invests in innovation, companies grow and hire, students gain experience, and communities benefit from new opportunities and long-term career pathways. Together with Governor Moore, the state of Maryland, and Anne Arundel County leaders, we are building a permanent path to long-term lunar operations, an advanced robotics and mechanisms center of excellence, and a technology edge for our nation.”

Intuitive Machines first launched operations in Maryland in 2021 and has since expanded five times in the state. The company officially opened its robotics and mechanisms facility in 2024.

The Maryland team has built robotics and mechanisms for the Nova-C landers and IM-1 and IM-2 missions. In the future, Intuitive Machines expects the Maryland team to work on its IM-3 Rover Deployment Mechanism (RDM), a 360 pan-tilt camera for panoramic views, the Main Engine Gimbal (MEG), and the company's first data relay satellite, known as Altus-1.

Intuitive Machines moved into a new $40 million headquarters at the Houston Spaceport in 2023. The company announced an expansion of its lease last year.

The company announced a $175 million equity investment to fuel growth in March. It's since landed a $180 million NASA CLPS award to deliver seven payloads to the moon's Mons Malapert on the IM-5 mission.
