Future Wearable Health techs May Measure Gases Released from the Skin'

Future wearable health technology may detect skin gas emissions. How? Let’s find out.

The newest generation of wearable health sensors has been developed by scientists, and they may be able to track a person’s health by sensing chemicals produced from their skin. The majority of studies that analyze human biomarkers—measure of a body’s health—use electrical impulses to detect the substances that are excreted in sweat. However, perspiration-based sensors sometimes need enormous volumes of them to provide a reading. Smartwatches and fitness trackers are examples of wearable technology that can already measure temperatures or pulse rates. However, a novel approach created by scientists at Ohio State University in the US would enable the device to detect biomarkers linked to metabolic illnesses including diabetes and heart disease.

What are wearables?

Electronic gadgets that customers may wear, such as Fitbits and smartwatches, are included in wearable technology in the healthcare industry. These gadgets are made to track users’ health and activity data. These gadgets can even instantly transmit a user’s medical data to a physician or other healthcare specialist. As more people express interest in sharing their wearable data with healthcare providers and insurers, the demand for wearables is anticipated to increase over the next several years. The medical sector, including insurers, providers, and technology firms, has been encouraged to produce more wearable devices like Fitbits, smartwatches, and wearable monitors due to the growth of wearable technology and the rising need for consumers to take charge of their health.

As per a senior investigator, Anthony Annerino who is a graduate in materials science and engineering, it is completely non-intrusive and inactive from the user’s perspective. According to research founder and director of materials science and engineering Pelagia-Iren Gouma, the ability to detect health issues via the skin is the final frontier.

The gadget would be a little gadget that a person might attach to low-sweat body areas such as behind the ear or on the nails, according to the study, which was an article in the journal PLOS One. Researchers have traditionally utilized the number of organic gases or molecules in our breath as a health indicator. One such tool that might be used to check someone out is a breathalyzer.

But according to Annerino, such a device necessitates “active purpose” and only offers a “momentary image” of the body. He asserted that this team’s sensors can function on far lower amounts of gaseous acetone emitted from the skin than the number of chemicals we exhale.

One of the compounds released by the skin, acetone, can provide researchers with a wealth of information on the inner workings of the human body. Blood sugar levels and fat-burning rates have also been demonstrated to be correlated with acetone concentrations in the breath. The researchers developed a film material using electroactive polymers and plant cellulose derivatives as sensors for testing. Depending on how much acetone is found in its surroundings, this film can flex significantly. The film was then exposed to ethanol (alcohol), acetone, and water solutions to test its sensitivity, selectivity, and repeatability. According to Annerino, “We discovered considerable bias toward bending more following exposure to particular compounds over others.” Depending on how much acetone is found in its surroundings, this film can flex significantly.

According to research co-author and materials science and engineering professor Pelagia-Iren Gouma, is the ability to detect health problems via the skin. Gouma is also the project manager for the Smart Connected Health initiative, which aims to promote medical and health research. Gouma stated that “the project still has a few years to go.” However, “we should have proof of concept in six months, and we’d want to have it tested in humans in a year.” The team’s study will ultimately result in a tiny gadget that may be worn on low-sweat body parts like the nails or behind the ear. Gouma anticipates that technology and medicine will advance even further as more individuals grow accustomed to utilizing wearable devices in their daily lives.

A new generation of skin sensors is being developed, and Gouma predicted that they will soon become the standard. Gouma is one of many scientists who have long used the concentration of organic chemicals in our breath, a sort of gas, as a health indicator. One illustration would be blowing into a breathalyzer, a machine that may monitor a person’s blood alcohol content or be used to find viruses. Irene Pelagia Gouma.
