UNITED KINGDOM – Researchers from the University of Bath have created an adhesive patch that measures the glucose levels of people with diabetes through their skin, according to a study published recently in Nature Nanotechnology. The patch draws glucose out from fluid between cells across hair follicles, which are individually accessed through an array of miniature sensors using a small electric current. The glucose collects in tiny reservoirs and is measured, and readings can be taken every 10 to 15 minutes over several hours. “The monitor developed at Bath promises a truly calibration-free approach, an essential contribution in the fight to combat the ever-increasing global incidence of diabetes,” said Richard Guy, one of the researchers, in a statement. The researchers hope the technology can eventually become a low-cost wearable sensor that sends glucose measurements to the patient’s phone or smartwatch, alerting them when they need to take action.
