Portable technologies are revolutionizing medical care, but design limitations in adhesive -based personal monitors have prevented them from fulfilling their full potential.
A new study by the University of Arizona, published in Nature communicationsDescribe a longer, printed and adhesive laptop without an adhesive capable of providing a more complete image of a user’s physiological state.
The device, which measures the water vapor and emissions of the skin of the gases, tracks and continuously record the physiological data associated with dehydration, metabolic changes and stress levels.
“The monitoring of laptop traditionally depends on the sensors that bind directly to the skin, but the skin itself is constantly renewed,” said Philipp Gutruf, associate professor of biomedical engineering and member of the Bio5 Institute in the U of a Co -author of the study with the main author David Clausen, a doctoral student and researcher at the Gutr Laboratory.
“This limits how much time can compile reliable data. With our sensor that tracks skin gaseous emissions, we overcome this restriction completely,” Gutruf said.
The detachment of the skin weakens adhesives and obstruction sensors, so the portable devices applied with adhesives must be applied again every few days. Researchers at the Gutruf laboratory in A A designed a device, used on the forearm, which resembles a small 3D printed bracelet and can be used continuously. The device sensors constantly measure gases emitted by the user, comparing their concentrations with normal outer air.
Unlike the portable health and health -based health monitoring devices, which historically only register snapshots, the device developed by Gutruf and its colleagues offer continuous and real -time data that can be seen on a smartphone or computer through Bluetooth sure.
“This opens a completely new space of biomarkers,” Gutruf said. “For example, you can capture the metabolic firms of exercise or stress without interrupting the normal routine of the subject. Previously, measurements of this type required a complete equipment room.”
Practical applications, proven results
With a device like this, athletes can monitor hydration and effort during training. The laptop could also record mental health symptoms and chronic disease to help prevention and treatment. In fact, the monitoring and monitoring of the physiological signs of stress in gas emissions can even help identify early metabolic disorders, Gutruf said.
“Our design is stable even when exposed to everyday movement and environmental changes,” Clausen said. “We can register data continuously for many days without recharging, all while we capture rich physiological data that are generally not possible in a portable format or require visible sweat.”
Researchers plan to expand the range of detectable biomarkers and integrate advanced data analysis to provide personalized health information for even longer periods.
The research was funded by the Arizona Technology and Research Initiative Fund, the Moore Foundation and with a discretionary award awarded to Gutruf as the 2024 Da Vinci member of the Faculty of Engineering.
