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."

Houston startup is off to the races with its innovative running shoes

running start

Despite Houston’s reputation as a sneaker town, there are few actual shoe companies headquartered in the Bayou City. One that is up and running is Veloci Running, an innovative enterprise that combines the founder’s history as a track runner for Rice University with the realities of running in a changing world.

Tyler Strothman started running cross country growing up in Wisconsin and Indiana before moving to Texas to attend Rice in 2020. Naturally, his college life was altered significantly by the COVID-19 pandemic. Unfortunately, Strothman contracted the virus, leading to pneumonia and causing him to consider other plans for his future.

One thing that stood out from Strothman’s running career was how bad his shoes fit.

“Traditional shoes narrowed in, cramped the front of my feet, and it was causing foot pain,” he said in a video interview. “But any other shoes that were shaped to better fit the natural foot shape were more barefoot (style)—they were more minimalist overall. And that was hurting my calf and Achilles. It was pulling on it, kind of like a rubber band.”

Strothman decided to start Veloci and went on to win the annual Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2025. The win secured $50,000 in startup money, which Strothman used to immediately launch his new runner-centered shoe design with himself as the CEO at the age of 24.

Along for the jog was Strothman’s college friend, Austin Escamilla, who serves as chief operating officer. Escamilla believed in Strothman’s vision, but the project immediately ran into snags beyond Veloci’s control, particularly with manufacturing in Asia.

“It was quite a year to start a shoe business, especially dealing with tariffs and global economic trade tensions,” he said in the same video interview. “We've luckily had some really good partners and really solid advisors throughout the journey who've either done it or had some good feedback and advice. It certainly takes a village, but every day is different. So, it's fun to come into work every day and problem solve.”

The flagship Veloci shoe is the Ascent, which comes in both men’s and women’s sizes. It combines the wide toe cage that Strothman wanted with extra support cushion for a softer, easier run. They retail at $180. Strothman has personally been testing them for a year, noticing reduced lower leg pain when he runs.

At the same time, Veloci has attended to some of the more unique running problems in Houston and other hot, Southern states. A combination of heat and humidity makes for a very soggy shoe if not designed with such environments in mind. The Ascent is built to be very open and breathable, allowing hot air to flow and keeping sweat from building up. These various comfort improvements have made the Ascent Strothman’s favorite running shoe.

“I put on more pairs of this Veloci shoe than I have in my other running shoes in the last seven years,” he said

Currently, Veloci is still a very niche brand. Since the company launched last year, they’ve sold roughly 10,000 pairs. Those sales come either directly through their website or from specialty running stores, most of which are located around the Houston area, like Clear Creek Running Company in League City.

Building community around the shoe through these specialty retailers has been a prime marketing strategy. Part of the $50,000 grant went to a custom van that Veloci can take to various 5Ks, runs and events to get people interested in the brand. The personal touch has helped news of Veloci spread through the running world.

“We went to many run clubs throughout the last year,” said Escamillia. “We've been to pretty much every one of the major run clubs at least once or twice. Folks who try on the shoes, love them, become fans and post and repost…. The marketing side's been a lot of fun.”

Intuitive Machines lands $180M NASA contract for lunar delivery mission

to the moon

NASA has awarded Intuitive Machines a $180.4 million Commercial Lunar Payload Services (CLPS) award to deliver science and technology to the moon.

This is the fifth CLPS award the Houston spacetech company has received from NASA, according to a release. It will be the first mission to utilize Intuitive Machines' larger cargo lunar lander, Nova-D.

Known as IM-5, the mission is expected to deliver seven payloads to Mons Malapert, a ridge near the Lunar South Pole, which is a "compelling location for future communications, navigation, and surface infrastructure," according to the release.

“We believe our space infrastructure provides the scalability and flexibility needed to support an increased cadence of new Artemis missions and advance national objectives. This CLPS award accelerates our expansion efforts as we build, connect, and operate the systems powering that infrastructure,” Steve Altemus, CEO of Intuitive Machines, said in the release. “We look forward to working closely with NASA to deliver mission success on IM-5 and to provide sustained operations and persistent connectivity in the cislunar environment and across the solar system.”

The delivery will include the Australian Space Agency’s lunar rover, known as Roo-ver, and another lunar rover from Honeybee Robotics, a part of Jeff Bezos' Blue Origin. Intuitive Machines will also deliver chemical analysis instruments, radiation detectors and other technologies, as well as a capsule named Sanctuary that shows examples of human achievements.

Intuitive Machines previously completed its IM-1 and IM-2 missions, which put the first commercial lunar lander on the moon and achieved the southernmost lunar landing, respectively.

Its IM-3 mission is expected to deliver international payloads to the moon's Reiner Gamma this year. It’s IM-4 mission, funded by a $116.9 million CLPS award, is expected to deliver six science and technology payloads to the Moon’s South Pole in 2027.

The company also announced a $175 million equity investment to fuel growth earlier this month.

TotalEnergies exits U.S. offshore wind sector in $1B federal deal

Energy News

TotalEnergies, a French company whose U.S. headquarters is in Houston, has agreed to redirect nearly $930 million in capital from two offshore wind leases on the East Coast to oil, natural gas and liquefied natural gas (LNG) production.

In its agreement with the U.S. Department of the Interior, TotalEnergies has also promised not to develop new offshore wind projects in the U.S. “in light of national security concerns,” according to a department press release.

Federal agency hails ‘landmark agreement’

The Department of the Interior called the deal a “landmark agreement” that will steer capital “from expensive, unreliable offshore wind leases toward affordable, reliable natural gas projects that will provide secure energy for hardworking Americans.”

Renewable energy advocates object to what they believe is the Trump administration’s mischaracterization of offshore wind projects.

Under the Department of the Interior agreement, the federal government will reimburse TotalEnergies on a dollar-for-dollar basis for the leases, up to the amount that the energy company paid.

“Offshore wind is one of the most expensive, unreliable, environmentally disruptive, and subsidy-dependent schemes ever forced on American ratepayers and taxpayers,” Interior Secretary Doug Burgum said in the announcement. “We welcome TotalEnergies’ commitment to developing projects that produce dependable, affordable power to lower Americans' monthly bills while providing secure U.S. baseload power today — and in the future.”

TotalEnergies cites U.S. policy in move away from U.S. wind power

In the news release, Patrick Pouyanné, chairman and CEO of TotalEnergies, says the company was “pleased” to sign the agreement to support the Trump administration’s energy policy.

“Considering that the development of offshore wind projects is not in the country’s interest, we have decided to renounce offshore wind development in the United States, in exchange for the reimbursement of the lease fees,” Pouyanné says.

TotalEnergies redirects capital to LNG, oil, and natural gas

TotalEnergies will use the $928 million it spent on the offshore wind leases for development of a joint venture LNG plant in the Rio Grande Valley, as well as for production of upstream oil in the Gulf of Mexico and for production of shale gas.

“These investments will contribute to supplying Europe with much-needed LNG from the U.S. and provide gas for U.S. data center development. We believe this is a more efficient use of capital in the United States,” Pouyanné says.

TotalEnergies paid $133.3 million for an offshore wind lease at the Carolina Long Bay project off the coast of North Carolina and $795 million in 2022 for a lease covering a 1,545-megawatt commercial offshore wind facility off the coast of New Jersey.

“TotalEnergies’ studies on these leases have shown that offshore wind developments in the United States, unlike those in Europe, are costly and might have a negative impact on power affordability for U.S. consumers,” TotalEnergies said in a company-issued press release. “Since other technologies are available to meet the growing demand for electricity in the United States in a more affordable way, TotalEnergies considers there is no need to allocate capital to this technology in the U.S.”

Since 2022, TotalEnergies has invested nearly $12 billion to promote the development of oil, LNG, and electricity in the U.S. In 2025, TotalEnergies was the No. 1 exporter of LNG from the U.S.

Industry groups push back on offshore wind pullback

The American Clean Energy Association has pushed back on the Trump administration’s characterization of offshore wind projects.

“The offshore wind industry creates thousands of high-quality, good-paying jobs, and is revitalizing American manufacturing supply chains and U.S. shipyards,” Jason Grumet, the association’s CEO, said in December after the Trump administration paused all leases for large-scale offshore wind projects under construction in the U.S. “It is a critical component of our energy security and provides stable, domestic power that helps meet demand and keep costs low.”

Grumet added that President Trump’s “relentless attacks on offshore wind undermine his own economic agenda and needlessly harm American workers and consumers.” He called for passage of federal legislation that would prevent the White House “from picking winners and losers” in the energy sector and “placing political ideology” above Americans’ best interests.

The National Resources Defense Council offered a similar response to the offshore wind leases being paused.

“In its ongoing effort to prop up waning fossil fuels interests, the administration is taking wilder and wilder swings at the clean energy projects this economy needs,” said Pasha Feinberg, the council’s offshore wind strategist. “Investments in energy infrastructure require business certainty. This is the opposite. If the administration thinks the chilling impacts of this action are limited to the clean energy sector, it is sorely mistaken.”
