With the latest wearable sweat sensors, patients will be able to adjust their medication level and diet plan with precise real-time information concerning their health.
FREMONT, CA: Technology has come up with a mass-producible wearable sensor that can check the metabolites and nutrients in the human blood by analyzing only their sweat. It is different from the previous sensors that were developed to aim at compounds that emerged in high concentrations. The new sweat sensor can distinguish sweat compounds even with lower levels, as well as are easy to manufacture.
As per the researchers, the sensors will allow the doctors to continually monitor the conditions of their patients with diabetes, kidney diseases, or cardiovascular diseases. It can follow the needs of the patients suffering from an illness that leads to abnormal levels of metabolites or nutrients in the bloodstream. The sensors can benefit the patients in several ways as they will be more informed about their situations, even when they attempt to stay away from encounters with hypodermic needles.
The new wearable sweat sensors can constantly and rapidly record the transformation carried out at the molecular levels and also allow personalized monitoring, time-to-time intervention, and early treatment of the patient’s needs.
The scientists focused on building devices that are based on microfluidics, tiny quantities of liquid influenced by technologies through channels that are less than a quarter of a millimeter. Microfluidics can additionally lessen the manipulation of sweat evaporation and skin contamination by sensing precision. The sensors can make more accurate sweat measurements and capture transient changes in concentrations.
In the past, most of the wearable sensors were based on microfluidic, made-up with the costly and complicated lithography-evaporation method. In recent times, the technological research teams have made their biosensors with graphene, a sheet-like structure of carbon.
Besides, the experts also planned their sensors with abilities that can measure heart rate, respiratory rate, and level of uric acid and tyrosine. Furthermore, the sensor can be used on patients at home to track their conditions like diabetes, cardiovascular diseases, or gout due to their high sensitivity and lower manufacturing expense. Patients can additionally adjust their medication level and diet plans with the help of real-time information, dealing with their health.
