The new wearer monitors your alcohol, blood sugar and pain levels with micro-needles.

Imagine the future, when you can take out your phone after a night of walking with your friends, consult a smartphone app connected to a wireless device in your hand, and find out how much you are a hammer. It sounds like something you will see in the first two minutes Black mirror The episode, however, has recently become a reality and can be a great help for people with any serious health conditions.

In a new study published in the journal on Monday Natural Biomedical Engineering, Researchers at the University of California, San Diego, have developed no more than a quarter to six devices that can detect alcohol, glucose and lactate. In addition to stating that Uber should be picked up from the bar instead of being driven home, the new wear equipment can help people with diabetes get accurate blood sugar levels.

“It’s like a complete laboratory in the skin,” said Joseph Wang, a biomedical engineer at the University of San Diego and author of the study, in a press release. “It is capable of continuously measuring multiple biomarkers at the same time, allowing users to monitor their health and well-being as they perform their day-to-day activities.”

Current wearable health sensors for people with diabetes are usually a trick pony. They can constantly monitor their blood glucose levels and do so very well, but there is little else. Although this information is clinically useful, it does not detail the dynamics of blood sugar and alcohol (which can lower blood sugar) or lactate (indicating muscle fatigue and tissue damage). A device that takes these factors into account allows a person with diabetes to better manage their health by optimizing their physical activity or drinking too much glass of wine.

“With our equipment, people can see the link between a sharp rise or fall in glucose through diet, exercise and alcohol consumption. It could also add to their quality of life, ”said Farshad Tehrani, a doctoral student at the University of San Diego and the first author of the study.

The device can be recharged on a ready-made wireless charging platform.

Another major disadvantage of wearable health monitors is that they rely on invasive needle-based sensors. Researchers at the University of San Diego used disposable micro-needles, which are painless and minimally invasive, about one-fifth the width of a person’s hair. Needles also contain sensors that can sample the interstitial fluid that sticks to your skin. This fluid fills the gaps between the cells and fills it with biological chemicals such as glucose, lactate and alcohol after drinking.

The various enzymes inside the magic micro-needles react with these chemicals to produce electrical signals. These signals are analyzed by additional sensors inside the device before they are sent wirelessly to a smartphone app developed by the researchers. When the new equipment was tested by volunteers eating, drinking, and exercising for five days, the data collected were identical to those collected using conventional blood glucose monitors or respirators.

Patrick Mercier, an electrical engineer and research co-author at UC San Diego, said in a press release: “The beauty of this is that it is a fully integrated system.

If you are in the market for this health-promoting sensor, you may have to wait a while for a commercially viable product. The device can only work for a few hours when recharging. The UC San Diego team plans to conduct more extensive clinical trials that could test the wearer’s ability to measure other health-related chemicals, such as antibiotic levels, in the treatment of bacterial infections.

However, when fully realized, researchers believe that their health sensor is promising not only for diabetics, but also for athletes who want to improve their physical performance, doctors who monitor their patients after organ transplants, and the general public. A home that likes to monitor health statistics. It’s like Fitbit in steroids.
