According to foreign media reports, stress has some mysterious effects on the human body. More and more studies have linked the existence of stress with various negative health consequences, including autoimmune diseases, diabetes, obesity and heart disease. Now scientists from the University of Cincinnati (UC) have developed a new sensor that can be used to monitor pressure levels, requiring only one drop of body fluid.
Prajokta Ray, the first author of the study and a UC graduate, said: "Pressure is harmful to us in many ways. It will sneak up on you. You don't know how much damage a short or long period of stress can be. Physical illnesses such as diabetes, high blood pressure, neurological or mental illness are caused by the stress experienced by the patient. And this is where I am interested."
To this end, Ray and his team set out to develop a new sensor that is easy to use and helps people understand their stress levels more clearly at home. It is reported that Ray's sensors are partly inspired by the experience of his colleague Andrew Steckl. Steckl is a professor of electrical engineering at the University of California who helped his father overcome stress-related health problems.
“I have to take him to the lab or the doctor to do tests to adjust his medication,” Steckl said. “I think if he can test it himself and see if he is in trouble, it’s great. Although this does not replace laboratory testing, it can tell patients more or less where they are."
The device works like a breakthrough sensor developed by Stanford University last year. This sensor measures cortisol levels in sweat samples, a hormone that responds to rising stress. The University of California team's equipment also measures cortisol, but only one drop of urine, blood, saliva or sweat can measure stress-related hormone levels such as serotonin, dopamine, norepinephrine and neuropeptides. It does this by tracking the optical absorbance of these biomarkers by ultraviolet spectroscopy.
However, Steckl said that this is not likely to replace a comprehensive laboratory blood test, but if you can test at home, this device can do it.
Medically, like the application of ultrasonic sensors, the team is now exploring the commercial possibilities of this new sensor and is working to turn it into a simple home testing tool so people can use it easily Check their stress hormones.
