Researchers at Pennsylvania State University have developed a sensor that monitors a person’s health by analyzing their sweat. Information about the new device is published in the journal Lab on a Chip.
The device will be interesting to representatives of the healthcare industry and, especially, athletes, as it can be used to control overheating or to adjust the optimal number of exercises. Researchers are also collaborating with representatives from the Pennsylvania State Medical School on disease monitoring. The device has one color-coded camera for pH, a second for glucose measurement, and a third for sodium. All three of these indicators are markers of the disease.
The device will be located on a device similar to a patch, it will be applied to the skin near the sweat glands. Inside there will be several chambers that have a hydrophobic, water-repellent, valve next to the silicone rubber hole. The channel has a hydrophilic, water-attracting coating for easy sweat collection. Unlike other devices requiring two holes, one hole reduces the amount of evaporation, which leads to an increase in the storage time of the liquid for subsequent analysis.
On-site analysis can be performed using the colorimetric approach, in which a color-coded analyte or, in other words, an analyte is preliminarily placed in the chambers. This sensitive chemical reacts to pH or glucose levels. In addition, researchers can analyze sweat at different points in time using various cameras called chrono-sampling.
