University of Houston professors identify super thin wearable device

Imagine a wearable device so thin it's less noticeable and lighter than a Band-Aid but can track and record important health information. According to some University of Houston researchers, you might not need to imagine it at all.

A recent paper, which ran as the cover story in Science Advances, identified a wearable human-machine interface device that is so thin a wearer might not even notice it. Cunjiang Yu, a Bill D. Cook associate professor of Mechanical Engineering at the University of Houston, was the lead author for the paper.

"Everything is very thin, just a few microns thick," says Yu, who also is a principal investigator at the Texas Center for Superconductivity at UH, in a release. "You will not be able to feel it."

The device is reported in the paper to be made of a metal oxide semiconductor on a polymer base. It could be attached to a robotic hand or prosthetic, as well as other robotic devices, that can collect and report information to the wearer.

"What if when you shook hands with a robotic hand, it was able to instantly deduce physical condition?" Yu asks in the release.

The device could also be used to help make decisions in situations that are hazardous to humans, such as chemical spills.

Current devices on the market or being developed are much slower to respond and bulkier to wear, not to mention expensive to develop.

"We report an ultrathin, mechanically imperceptible, and stretchable (human-machine interface) HMI device, which is worn on human skin to capture multiple physical data and also on a robot to offer intelligent feedback, forming a closed-loop HMI," the researchers write in the paper. "The multifunctional soft stretchy HMI device is based on a one-step formed, sol-gel-on-polymer-processed indium zinc oxide semiconductor nanomembrane electronics."

The paper's co-authors, in addition to Yu, include first author Kyoseung Sim, Zhoulyu Rao, Faheem Ershad, Jianming Lei, Anish Thukral, and Jie Chen, who are all from UH; Zhanan Zou and Jianliang Xiao of the University of Colorado; and Qing-An Huang of Southeast University in Nanjing, China.

Building Houston

A new Houston-based digital advanced care planning company is streamlining some of the most difficult conversations in the health care industry around palliative care.

Founded by Tatiana Fafanova, Dr. Desh Mohan, and Katelin Cherry, Koda Health uses AI to help patients create advance medical care directives and documents—such as a living will—through an easy to use web-based interface.

Koda Health uses a conversational platform where users can enter information about their values, living situations, quality of life wishes, and more while learning about different care options at their own speed. It also uses a proprietary machine learning approach that personalizes audio-video guided dialogue based on the patient's individual and cultural preferences.

The app then autogenerates legal and medical documents, which patients can notarize or electronically witness the forms through the app or on their own.

According to Fafanova, who earned her PhD in in Molecular Medicine at Baylor College of Medicine in Houston and now acts as the company's CEO, what historically has been a time consuming and expensive process, through Koda Health, takes an average of 17 minutes and is completely free of charge to the end user.

"We hope to reduce any outstanding barriers to access that might exist," Fafanova says. "It is very frequently the oldest and the poorest that are the highest utilizers of health care that don't have access to these solutions."

The app is also projected to save health care systems roughly $9,500 per patient per year, as it allows for hospitals and organizations to better plan for what their patient population is seeking in end-of-life-care.

The B2B platform was born out of the TMC's Biodesign Fellowship, which tasked Koda's founding members with finding solutions to issues surrounding geriatric care in the medical center. In March 2020, Koda incorporated. Not long after ICU beds began to fill with COVID-19 patients, "galvanizing" the team's mission, Fafanova says.

"It was no longer this conceptual thing that we needed to address and write a report on. Now it was that people were winding up in the hospital at alarming rates and none of those individuals had advanced care planning in place," she says.

After accelerating the development of the product, Koda Health is now being used by health care systems in Houston, Texas, and Virginia.

The company recently received a Phase I grant of $256,000 from the National Science Foundation, which will allow Koda to deploy the platform at Atrium Health Wake Forest Baptist and test it against phone conversations with 900 patients. Fafanova says the company will also use the funds to continue to develop personalization algorithms to improve Kona's interface for users.

"We want to make this a platform that mimics a high quality conversation," she says.

After Koda completes the Phase I pilot program it will then be eligible to apply for a Phase II award of up to $1 million in about a year.
