Description:
Paper-based self-powered sensor patch for glucose monitoring in sweat and for the prevention and management of exercise-induced hypoglycemia
Background:
However, such physical exertion can increase the risk of hypoglycemia in insulin-dependent diabetes mellitus, causing irritability, confusion, and even seizures and unconsciousness. Today’s most widespread methods for glucose self-testing involves monitoring the blood glucose levels. Such techniques use a lancet device to manually prick the skin for the blood sample. Then, the sample is positioned onto a disposable test strip, which is inserted into a portable glucometer to read an electrochemical signal and calculate the blood glucose levels. However, the conventional measurements are not suitable for preventing hypoglycemia during exercise.
Technology Overview:
The present invention provides a paper-based self-powered sensor patch for glucose monitoring in sweat and for the prevention and management of exercise-induced hypoglycemia. The technology demonstrates the sensing concept for self-powered, wearable, and disposable glucose monitoring in sweat. The fuel cell-based sensor is composed of three functional layers: the anodic layer with a conductive reservoir, the sweat reservoir, and the air-cathode layer. When attached directly to human skin, sweat is wicked by using capillary forces and monitored an electrochemical current generation as a transducing output signal for glucose monitoring in sweat. Thus, it eliminates the requirement of exterior batteries and advances readout instrumentation.
