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 doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
