A recent University of Houston graduate is receiving international recognition for his 3D-printable finger prosthesis.

David Edquilang, the creator of a low-cost prosthesis known as Lunet, was awarded the 2023 Red Dot: Luminary award last month at the Red Dot Award: Design Concept ceremony in Singapore. The luminary award is the highest recognition given at the international event, according to a release from UH.

Edquilang, who graduated from UH in 2022, developed Lunet while he was a student at the Gerald D. Hines College of Architecture and Design and under the mentorship of UH associate professor and co-director of the Industrial Design program Jeff Feng.

The prosthesis is made up of polylactic acid and thermoplastic polyurethane, two common types of 3D-printed plastics, and designed to be simple but essentially indestructible.

Lunet's "fingers" are made of four parts held together by plastic pins, compared to other prosthetics that feature many different parts and require metal fasteners, adhesives or tools.

“The problem with higher mechanical complexity is that these designs are less durable,” Edquilang says in the statement. “The more parts you have, the more points of failure. You need to make prosthetic fingers robust and as strong as possible, so it doesn’t break under normal use, yet you want the design to be simple. This was one of the greatest challenges in making Lunet.”

Lunet is also unique in that it includes a linkage mechanism that allows the fingers' distal knuckle (closest to the fingertip) to be more flexible, and even partially hyperextend backward to be more durable and realistic.

What's perhaps the rarest component of Lunet is that Edquilang has made it open access on the internet.

“Not every good idea needs to be turned into a business. Sometimes, the best ideas just need to be put out there,” Edquilang adds. “Medical insurance will often not cover the cost of a finger prosthesis, since it is not considered vital enough compared to an arm or leg. Making Lunet available online for free will allow it to help the greatest number of people."

The concept was born after Edquilang worked on an upper limb prosthesis with fellow UH student Niell Gorman. After that project wrapped, Edquilang, in partnership with Harris Health System, began designing a prosthetic hand for a woman who had lost three fingers due to frostbite. Edquilang and Feng continued to refine the product, and after conceptualizing the breakthrough idea for the flexible linkage for the distal knuckle, Lunet became what it is today.

The product has also won a 2023 Red Dot: Best of the Best award, two 2023 DNA Paris Design Awards, Gold for the 2023 Spark Design Award, and is currently a U.S. National Runner Up for the 2023 James Dyson Award.

“It feels great knowing you have the capability to positively impact people’s lives and give them help they otherwise wouldn’t be able to get,” Edquilang says.

This summer UH researchers also published their work on a wearable human-machine interface device that can track and record important health information but is less noticeable and lighter than a Band-Aid. The device could be attached to a robotic hand or prosthetic, as well as other robotic devices that can collect and report information to the wearer.

Also this summer, a team from Rice published their work on a new system of haptic accessories that rely heavily on fluidic control over electrical inputs to signal or simulate touch to a wearer. The technology, which was backed by the National Science Foundation, has uses for those with visual and auditory impairments and offers a slimmed-down design compared to other bulky complex haptic wearables.

Houston team develops low-cost device to treat infants with life-threatening birth defect

infant innovation

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.

Generally, a single-use bag can cost between $200 and $300. The alternatives that exist lack structure and require surgical sewing. This is where the SimpleSilo comes in.

“We focused on keeping the design as simple and functional as possible, while still being affordable,” Vanshika Jhonsa said in a news release. “Our hope is that health care providers around the world can adapt the SimpleSilo to their local supplies and specific needs.”

The study was published in the Journal of Pediatric Surgery, and Jhonsa, its first author, also won the 2023 American Pediatric Surgical Association Innovation Award for the project. She is a recent Rice alumna and is currently a medical student at UTHealth Houston.

Bindi Naik-Mathuria, a pediatric surgeon at UTMB Health, served as the corresponding author of the study. Rice undergraduates Shreya Jindal and Shriya Shah, along with Mary Seifu Tirfie, a current Rice360 Global Health Fellow, also worked on the project.

In laboratory tests, the device demonstrated a fluid leakage rate of just 0.02 milliliters per hour, which is comparable to commercial silo bags, and it withstood repeated disinfection while maintaining its structure. In a simulated in vitro test using cow intestines and a mock abdominal wall, SimpleSilo achieved a 50 percent reduction of the intestines into the simulated cavity over three days, also matching the performance of commercial silo bags. The team plans to conduct a formal clinical trial in East Africa.

“Gastroschisis has one of the biggest survival gaps from high-resource settings to low-resource settings, but it doesn’t have to be this way,” Meaghan Bond, lecturer and senior design engineer at Rice360, added in the news release. “We believe the SimpleSilo can help close the survival gap by making treatment accessible and affordable, even in resource-limited settings.”

Oxy's $1.3B Texas carbon capture facility on track to​ launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.
