Your skin doesn't just shine – it's Gussy. And now science is sniffing it out.
Northwestern University researcher Developed The world's first contactless device that allows you to monitor your health by measuring gases that are naturally released and absorbed without touching your skin.
“This technology has the potential to transform clinical care, especially for vulnerable populations, including newborns, elderly people, diabetics and other skin compromises,” he said. Dr. Guillermo A. Amiaa professor of biomedical engineering who co-led with the research.
Secret Signal
Your skin is not just a barrier. It is a two-way street between your body and the outside world.
Every day, gases such as carbon dioxide, water vapor, oxygen and volatile organic compounds (VOCs) also protect against irritants, toxins and allergens in the environment.
The device, developed by researchers at Northwestern, monitors all its activities without even placing your finger on you, opening a new window to skin health.
It's small but powerful
The gadget is small, only 2 cm long and 1.5 cm wide, and is equipped with a sensor that pulls gas samples through a mini air chamber floating just above the skin without contact.
It's a game changer, as most wearable devices need to stick directly to the skin. This can be a challenge for people with vulnerable or damaged organizations.
The data it collects can provide insight into everything from wound healing and hydration levels to early signs of infection, to even exposure to toxic chemicals.
“For workers in potentially dangerous environments, knowing how much of these dangerous species are in the body through the skin is helpful,” he said. Dr. John Rogersa Northwestern professor and researcher co-led the research.
Real-time monitoring with your fingertips
One of the biggest perks of compact wearables is that patients can manage their skin health at home and eliminate the need for bulky, traditional hospital equipment.
Better yet, it syncs with your smartphone or tablet to provide real-time data on the gases your skin is exuding and absorbing.
The researchers said this rapid, accessible information would help healthcare providers make faster and more informed treatment decisions. This is especially important for wound healing.
“Prescribing antibiotics for wounds can be a bit of a gamble,” Ameer says. “It can be difficult to tell if a wound is infected or not. By the time it becomes clear, it may be too late and patients may develop sepsis, which is extremely dangerous.”
As increased water vapor, CO2, and VOCs are associated with slower bacterial growth and healing, researchers said monitoring these factors would help caregivers detect infections faster and more accurately, allowing faster interventions and better health outcomes.
“It's clear and important to be able to monitor the wound closely and prescribe antibiotics at the earliest signs of infection,” Ameer said.
Next Steps
The Northwestern team envisions bug repellents, skin care products and devices used to increase the effectiveness of medications designed to improve skin health.
For example, CO2 and VOC attract mosquitoes and other pests. By measuring these emissions from the skin, it helps scientists develop better strategies to keep them apart.
The device helps dermatologists measure how quickly lotions and creams penetrate the skin, and also helps researchers assess the safety of cosmetics and personal care products.
Looking ahead, researchers hope to improve the device's capabilities, including adding sensors to monitor changes in PH levels and creating gas sensors with chemoselectivity for early detection of organ dysfunction and other diseases.
“The technique is not about measuring gas and measuring the corresponding properties of the skin,” Rogers said.
“It's about predicting overall health, preventing infections and illnesses, and creating a future where personalized care is driven by real-time, non-invasive, continuous health tracking,” he continued.
