Richard Guy and University of Bath colleagues have created a non-invasive, adhesive patch, to measure glucose levels through the skin without a finger-prick blood test.
The patch draws glucose from fluid between cells across hair follicles, accessed individually via an array of miniature sensors using a small electric current. The glucose collects in tiny reservoirs and is measured. Readings can be taken every 10 to 15 minutes over several hours. Calibration with a blood sample is not required.
The goal is the development of a low-cost, wearable sensor that sends regular, clinically relevant glucose measurements to one’s phone or watch, with alerts when action is required.
